Scandium Metal Sc Metal CAS 7440-20-2

About Scandium Metal Sc Metal:
Scandium is a chemical element with the element symbol Sc and an atomic number of 21. Is scandium a metal? A silvery metal that tarnishes in air, burns easily and reacts with water. Scandium is mainly used for research purposes. It has, however, great potential because it has almost as low a density as aluminum and a much higher melting point. Elemental is a soft, silvery-white transition metal, often mixed with gadolinium, erbium and other existence, the yield is very small, in the earth's crust content is about 0.0005%. Why is scandium so expensive? Owing to its scarcity and limited production, scandium is one of the most expensive of all the natural elements.
Is scandium harmful to humans? Health effects of scandium: Scandium is most dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure. Scandium can be a threat to the liver when it accumulates in the human body.
Scandium is commonly used to make special glass, light and high-temperature resistant alloys. Scandium is slightly yellowish or pink when oxidized by air, is easily weathered and slowly dissolves in most dilute acids. However, in strong acids, the surface tends to form an impermeable passivation layer, so it does not react with a 1:1 mixture of nitric acid (HNO3) and hydrofluoric acid (HF).

In the metal-insulator-semiconductor silicon photocell and solar cell, scandium is the best barrier metal.
Alloy industrial
Scandium, in its elemental form, has been widely used in the doping of aluminum alloys. As long as a few thousandths of scandium is added to aluminum, a new phase of Al3Sc will be formed, which will have metamorphism on aluminum alloy and make the structure and properties of the alloy change significantly. The addition of 0.2%~0.4% Sc can increase the recrystallization temperature of the alloy by 150~200℃, and the high-temperature strength, structural stability, welding property and corrosion resistance are obviously improved and can avoid the embrittlement phenomenon which is easy to occur in the long-term working at high temperature.
To change the agent
Scandium is also an excellent iron modifier. A small amount of Scandium can significantly improve the strength and hardness of cast iron. In addition, scandium can also be used as an additive in high-temperature tungsten and chromium alloys.
Ceramic materials
The elemental scandium is generally used in alloys, and the oxide of scandium also plays an important role in ceramic materials. Tetragonal zirconia ceramics, such as those that can be used as electrode materials for solid oxide fuel cells, have a very special property in which the conductance of this electrolyte increases with temperature and oxygen concentration in the environment.
The catalytic chemistry
In the chemical industry, scandium is often used as a catalyst, SC2O3 can be used for ethanol or isopropanol dehydration and deoxygenation, acetic acid decomposition, from CO and H2 ethylene and so on. The Pt-Al catalyst containing SC2O3 is used as an important catalyst in the hydrogenation purification and refining process of heavy oil in the petrochemical industry.
Nuclear power industry
Adding a small amount of SC2O3 to UO2 in high-temperature reactor nuclear fuel can avoid lattice transition, volume increase and crack caused by UO2 to U3O8 conversion.
A fuel cell
Similarly, the addition of 2.5%~25% scandium in the nickel base battery will increase the service life.
Agricultural breeding
In agriculture, corn, beet, pea, wheat, sunflower and other seeds can be treated with scandium sulfate (the concentration is generally 10-3~10-8mol/L, different plants will be different). The actual effect of promoting germination has been achieved. After 8 hours, the dry weight of root and bud is increased by 37% and 78%, respectively, compared with that of seedlings.

Boride Powder

Magnesium Diboride MgB2 Powder CAS 12007-25-9

About Magnesium Diboride MgB2 Powder:
Magnesium diboride is an inorganic compound with the molecular formula MgB2. It is a dark gray, insoluble solid. It is an ionic compound with a hexagonal crystal structure. It is an intercalated compound with alternating layers of magnesium and boron. This compound is of interest because it is superconducting at 39 K(−234°C).In terms of composition, MgB2 is markedly different from most transition-metal-based cryogenic superconductors.

Magnesium diboride has been known to scientists for nearly 50 years, but no one has ever studied the material's superconductivity -- whether it can conduct electricity perfectly without resistance when cooled to temperatures close to absolute zero. All that changed in January 2001, when Jun Akimitsu of Aoyama Gakuin University in Tokyo announced that he and his team had found that magnesium diboride became superconducting at 39 degrees Kelvin (-389 degrees Fahrenheit), almost twice the temperature of current intermetallic conductors. The announcement sent experimenters around the world scrambling to replicate and confirm the Japanese findings.

Magnesium boride is converted into a superconductor at a temperature slightly close to the absolute temperature of 40K (-233 ° C). Its transition temperature is nearly twice as high as that of other superconductors of the same type, and its actual operating temperature is between 20 and 30K. This temperature can be achieved by liquid neon, liquid hydrogen, or a closed cycle freezer. These methods are simpler and cheaper than the industry's use of liquid helium to cool niobium alloys (4K). Once doped with carbon or other impurities, magnesium boride is as good at maintaining superconductivity in the presence of a magnetic field or a current as niobium, or better. Feel free to send an inquiry to get the latest price if you would like to buy Magnesium Diboride MgB2 Powder in bulk.

Magnesium diboride is an ionic compound, with the hexagonal crystal structure. Magnesium diboride at absolute temperature slightly 40K (equivalent to -233 ℃) will be transformed into a superconductor. And its actual operating temperature is 20 ~ 30K. To reach this temperature, we can use liquid neon, liquid hydrogen or closed-cycle refrigerator to finish cooling. Compared to current industry using liquid helium to cool the niobium alloy (4K), these methods are more simple and economical. Once it is doped with carbon or other impurities, magnesium diboride in a magnetic field, or there is a current passing, the ability to maintain the superconducting is as much as niobium alloys, or even better.

How is Magnesium Diboride MgB2 Powder produced?
The preparation method of MgB2 is mainly the reaction synthesis of magnesium powder and boron powder mixed.
MgB2 was obtained by mixing 99.9% magnesium powder with 99% amorphous boron powder at the ratio of 1:2, pressing it into small balls and adding heat in high-pressure nitrogen.

At present, the commonly used method is to mix amorphous elemental boron powder and magnesium powder according to the stoichiometric ratio (or add excessive magnesium), and then put them into a sealed refractory metal container (such as tantalum), and then put them in a quartz tube for vacuum pumping, and then sintered at 700~950℃ for 1~4 h to synthesize MgB2.

Applications of Magnesium Diboride MgB2 Powder:
Potential applications for Magnesium diboride include superconducting magnets, power transmission lines and sensitive magnetic field detectors.

Magnesium diboride is the attention of new materials, the research mainly focused on the synthesis and superconducting element performance for the industrial synthesis and sintering properties, electrical conductivity at room temperature, the liquid aluminum erosion resistance of fluoride such as corrosive resistance study is less, so far no will MgB2 and its composite materials used in aluminum electrolysis cathodic area coverage.

MgB2 is easier to be sintered and densified than TiB2, and its electrical conductivity basically meets the requirements of aluminum electrolysis cathode. Therefore, MgB2 and its composite materials are likely to be widely used as cathode materials for aluminum electrolysis.

Propellants, Explosives, pyrotechnics: Unlike the element boron, which burns incompletely through glass oxide layers that block oxygen diffusion, magnesium diboride burns completely in oxygen or oxidizer mixtures. Therefore, magnesium boride has been proposed as fuel for ramjet jets. In addition, the use of MgB2 in enhanced explosives and propellants has been proposed for the same reason.

Storage Conditions of Magnesium Diboride MgB2 powder

This product should be sealed and stored in a cool, drying chamber and should avoid exposure to the air in order to prevent moisture reunion which will affect the dispersion properties and result use. Stress should be avoided.

Packing & Shipping of Magnesium Diboride MgB2 powder:
We have many different kinds of packing which depend on the magnesium diboride MgB2 powder quantity.
Magnesium diboride MgB2 powder packing:vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.

Tungsten boride has comprehensive properties such as high melting point, high hardness and chemical stability. It is only a new superhard material with a high melting point. It is an important military bulletproof material.
For more than 50 years, it has been considered that the rich phase diagram of tungsten alloys, the structure of different phases is also ever-changing.
The highest boride is WB4, which has a three-dimensional grid structure of boron atoms. We put the first the principle calculation is combined with the thermodynamic stability, and the thermodynamic stability and mechanical properties of the possible structure of the tungsten carbide system are systematically studied:
The highest boride to identify tungsten should be WB3 composed of two-dimensional plane boron atoms, not WB4 composed of three-dimensional boron atom grids. It was found that the shear modulus in the borate system of tungsten transformed its formation energy. Increase, revealing that the mechanical properties are closely related to their thermodynamic stability.
Due to the free diffusion coefficient of WB2, the total synthesis of dense tungsten diboride is mostly achieved by sintering technology under high temperature and high-pressure conditions. In this way, it is reduced and the cost is too high; instead, because B will volatilize at high temperature.
Therefore, it is difficult to grasp the content of boron to prepare WB2 bulk materials directly from tungsten powder and boron powder.
It may also generate hypoborate during the sintering process, and compact bulk material with WB2 as the main phase cannot be obtained. Feel free to send an inquiry to get the latest price if you would like to buy Tungsten Boride WB2 powder in bulk.

Boride Powder

Calcium Hexaboride CaB6 Powder CAS 12007-99-7

About Calcium Hexaboride CaB6 Powder:
Calcium hexaboride (calcium boride) is a compound of calcium and boron, with the chemical formula CaB6. Due to its high conductivity, hardness, chemical stability and melting point, it is an important material. It is a black, shiny, chemically inert powder with low density. It has a typical cubic structure of six metal boride, with octahedral units of six boron atoms and calcium atoms.

CaB6 has been investigated in the past due to a variety of peculiar physical properties, such as superconductivity, valence fluctuation and Kondo effects. However, the most remarkable property of calcium boride is its ferromagnetism. It occurs at unexpectedly high temperatures (600K) and with a low magnetic moment. The origin of this high-temperature ferromagnetism is the ferromagnetic phase of the dilute electron gas, linkage to the presumed excitonic state in calcium boride, or external impurities on the surface of the sample. The impurities might include iron and nickel, probably coming from impurities in the boron used to prepare the sample.

CaB6 is insoluble in H2O, MeOH (methanol), and EtOH (ethanol) and dissolves slowly in acids. Its microhardness is 27 GPa, Knoop hardness is 2600 kg/mm2), the Young modulus is 379 GPa, and electrical resistivity is greater than 2·1010 Ω·m for pure crystals. CaB6 is a semiconductor with an energy gap estimated at 1.0 eV. The low, semi-metallic conductivity of many CaB6 samples can be explained by unintentional doping due to impurities and possible non-stoichiometry. Feel free to send an inquiry to get the latest price if you would like to buy Calcium Hexaboride CaB6 Powder in bulk.

Product Performance of Calcium Hexaboride CaB6 Powder:

Calcium boride has the characteristics of high melting point and high hardness. Its physical and chemical properties are quite stable. When calcined in air, sub-micron CaB6 will only gain weight after 800 degrees Celsius and is not easy to oxidize. CaB6 is generally insoluble in hydrochloric acid and sulfuric acid, so technically to remove impurity materials by hot hydrochloric acid, but CaB6 is soluble in nitric acid.

How is Calcium Hexaboride CaB6 Powder produced?
One of the main reactions of industrial production is:
CaO + 3 B2O3 + 10 Mg→CaB6 + 10 MgO
Other methods of producing CaB6 powder include:

Calcium or calcium oxide reacts directly with boron at 1000°C;
Ca + 6B→CaB6
Ca(OH)2 reacts with boron under a vacuum of about 1700°C (carbothermal reduction);
Ca（OH）2 + 7B→CaB6 + BO（g）+ H2O（g）
The reaction of calcium carbonate and boron carbide under vacuum above 1400°C (Carbothermal reduction)
CaO and H3BO3 react with Mg to 1100°C.
Low temperature (500°C) synthesis
CaCl2 + 6NaBH4→CaB6 + 2NaCl + 12H2 + 4Na
As a result, the material quality is relatively poor.

In order to produce, for example, pure calcium boride single crystals used as cathode materials, the CaB6 powder thus obtained is further recrystallized and purified by zone melting technology. The typical growth rate is 30 cm/h, and the crystal size is about 1x10 cm.
Single crystal CaB6 nanowires (diameter 15-40 nm, length 1-10 microns) can be obtained by pyrolyzing diborane (B2H6) on calcium oxide (CaO) powder at 860-900°C in the presence of Ni catalyst.

1. Used as a boron-containing additive for dolomite charcoal and magnesium dolomite charcoal refractories to resist oxidation, erosion and improve the thermal strength.
2. Used as a deoxidizing and degassing agent for highly conductive red copper to improve conductivity and strength.
3. Used as a new type of material for preventing neutrons in the nuclear industry.
4. Used as a new type of semiconductor material in spin electronic components with a temperature of 900K.
5. Used as a raw material for manufacturing boron trichloride (BCl3) and amorphous boron.
6. Used as a raw material for manufacturing high-purity metal borides (TiB2, ZrB2, HfB2, etc.) and high-purity boron alloys (Ni-B, Co-B, Cu-B, etc.).
7. Used to manufacture a mixture of catalyst-containing calcium-boron nitride (Ca3B2N4) and hexagonal boron nitride, and to produce crystal cubic boron nitride with excellent performance.

Boride Powder

Zirconium Diboride ZrB2 Powder CAS 12045-64-6

About Zirconium Diboride ZrB2 Powder:
Zirconium boride powder is a chemical substance and its molecular formula is ZrB2. Nature gray hard crystals. Zirconium boride has three components: zirconium monoboride, zirconium diboride, and zirconium tribromide. Only zirconium diboride is stable in a wide temperature range. Industrial production is mainly based on zirconium diboride. Zirconium diboride is a hexagonal crystal, gray crystal or powder, with a relative density of 5.8 and a melting point of 3040°C. High-temperature resistance, high strength at room temperature and high temperature. Good thermal shock resistance, low resistance, anti-oxidation at high temperature. The melting point is about 3000°C. With metallic luster.

Zirconium diboride powder(ZrB2) is a highly covalent refractory ceramic material with a hexagonal crystal structure. ZrB2 is an ultra-high temperature ceramic (UHTC) with a melting point of 3246°C. Coupled with a lower density of ~6.09 g/cm3 (the measured density may be higher due to ha impurities) and good high-temperature strength, it is suitable for high-temperature aerospace applications, such as hypersonic flight or rocket propulsion systems, for example, Furnace components, high-temperature electrodes, rocket engines, thermal protection structures for spacecraft with temperature capabilities exceeding 1800°C, and heavy-wear applications.

It is an unusual ceramic with relatively high thermal and electrical conductivity and has the same characteristics as the titanium diboride and diboride shares of the same structure. In addition to its fire resistance, good thermal conductivity (>50 W/m/K), inertness to molten metal, good thermal shock resistance, and high electrical conductivity (~105 S/cm), ZrB2 can also pass EDM basic ceramic molding.

ZrB2 parts are usually hot-pressed (applying pressure to the heated powder) and then machined to form. The covalent nature of the material and the presence of surface oxides hinder the sintering of ZrB2. The presence of surface oxides will increase the coarsening of crystal grains before densification during the sintering process. Pressureless sintering of ZrB2 is possible. Sintering additives such as boron carbide and carbon will react with surface oxides, thereby increasing the driving force for sintering, but the mechanical properties will decrease compared to hot-pressed ZrB2. Feel free to send an inquiry to get the latest price if you would like to buy Zirconium Diboride ZrB2 Powder in bulk.

Zirconium diboride (ZrB2) is a highly covalent refractory ceramic material with a hexagonal crystal structure. ZrB2 is an ultra high temperature ceramic (UHTC) with a melting point of 3246 °C. This along with its relatively low density of ~6.09 g/cm3 (measured density may be higher due to hafnium impurities) and good high temperature strength makes it a candidate for high temperature aerospace applications such as hypersonic flight or rocket propulsion systems. It is an unusual ceramic, having relatively high thermal and electrical conductivities, properties it shares with isostructural titanium diboride and hafnium diboride.

How is Zirconium Diboride ZrB2 Powder produced?
ZrO2 and HfO2 are reduced to their respective diboron silanes by metal thermal reduction. Use cheap precursor materials and react according to the following reactions:

ZrO 2 + B 2 O 3 + 5Mg→ZrB 2 + 5MgO

The precursor materials for this reaction (ZrO 2 / TiO 2 / HfO 2 and B 4 C) are cheaper than those required for stoichiometric and boron thermal reactions. Prepare ZrB2 at a temperature higher than 1600°C for at least 1 hour through the following reaction:

2ZrO 2 + B 4 C + 3C→2ZrB 2 + 4CO

This method requires a slight excess of boron because some boron is oxidized during the boron carbide reduction process. It is also observed that ZrC is the product of the reaction, but if the reaction is carried out under an excess of 20-25% of B4C, the ZrC phase disappears and only ZrB2 remains. The lowest synthesis temperature (~1600°C) will produce UHTC with finer dimensions and better sinterability. Before boron carbide reduction, the boron carbide must be ground to promote the oxide reduction and diffusion process.

ZrO2 and HfO2 can be dispersed on the boron carbide polymer precursor before the reaction. in. Heating the reaction mixture to 1500°C results in the formation of boron carbide and carbon in situ, and the subsequent reduction of ZrO2 to ZrB2.

The gas phase is used to reduce the vapors of zirconium tetrachloride and boron trichloride when the substrate temperature is higher than 800°C. Recently, alternative ZrB2 films can also be prepared by physical vapor deposition.

Applications of Zirconium Diboride ZrB2 Powder:
Zirconium boride has high hardness, high thermal conductivity, good oxidation resistance and good corrosion resistance. Zirconium diboride is used in special ceramic refractory industries, nuclear industry, aerospace industry and military industries. Zirconium diboride can be used as a surface coating for rolling balls and smooth solid materials.

Carbon fiber reinforced zirconium diboride composites exhibit high density, while silicon carbide fiber-reinforced zirconium diboride composites are brittle and show catastrophic damage.

Zirconium diboride (ZrB2) can be used as thin-film electronic components for sensors, actuators and micro-systems operating in high-temperature environments because it has metal-like conductivity and has a melting temperature of 3245°C.
Other applications of Zirconium Diboride ZrB2 Powder:
