About Lithium Battery Anode Material 99.95% Natural Composite Graphite 216:
Natural graphite is a natural mineral, which is generally formed in high-temperature geological conditions and widely distributed in metamorphic deposits. It is formed by the regional metamorphism of sedimentary rocks rich in organic matter or carbon. Generally can be divided into crystalline graphite (flake) and cryptocrystalline graphite (earthy)

The technological properties and uses of graphite are mainly determined by the degree of crystallization. Natural graphite can be divided into crystalline graphite (flake graphite) and cryptocrystalline graphite (earthy graphite) according to its crystalline form.
Crystalline graphite

In crystalline (flaky) graphite ores, the graphite crystals are larger than 1μm in diameter and are flaky. The ore grade is low, but the benefits ability is good. The minerals associated with graphite are often mica, feldspar, quartz, tremolite, diopside, garnet and a small amount of pyrite, calcite, etc., and some are associated with rutile and vanadium and other useful components; The ore is of flake, granitic scale or granular last crystalline structure, flake, gneiss or massive structure.

Cryptocrystalline graphite
Cryptotite ink is also known as earth-like graphite or amorphous graphite. In cryptocrystalline graphite ore, graphite crystal diameter is less than 1μm, showing an aggregate of microcrystals, and crystal shape can be seen under an electron microscope; The ore has high grade but poor separability.

The Properties And Application of boron carbide

What exactly does boron carbide mean? Boron carbonide also known as black-diamond, is a powder with a molecular formula B4C. This usually results in a greyish black powder. It is one the three most hard materials (the others being diamond and cubic boron nutride) and it is used in body armor, tank armor, and other industrial applications. Its Mohs Hardness is 9.3. Due to its low density, strength, high stability, and high chemical stability, Useful in ceramic reinforced phase, wear-resistant materials and reactor neutron absorbers. Boron carbide has a lower cost of production than cubic boron, which is why it is widely used. Boron carbide can sometimes replace diamonds and it is used for grinding, drilling, and other purposes. Application of Boron carbide 1.Control nuclear fission Boron carbide has the ability to absorb large quantities of neutrons while not forming radioisotopes. This makes it an ideal neutron absorber in nuclear power stations. The neutron absorbers control nuclear fission's rate. Although it can usually be made into rods in the reactor yard, some people make powdered Boron Carbide due to the larger surface area. Russia had nearly 2,000 tonnes of boron carbide, sand and other materials dropped on the Chernobyl nuclear incident in 1986. Then, the chain reaction was stopped at the reactor. 2.Abrasive material The use of boron carbide as coarse abrasive materials has existed for quite some time. Because of its high melting point it is hard to make artificial products from it. But, by melting it at high temperature it can still be transformed into simpler shapes. This is useful for polishing and drilling hard materials, such as precious and cemented stones and cement carbide. 3.Coating Boron carbide can be used to coat warships or helicopters with ceramics. The material is lightweight, and it can resist armor-piercing bullets. 4.nozzle You can use it as an arm industry gun nozzle. Boron carbide can be used as a gun nozzle in the arms industry. It has an extremely high wear resistance and density. Due to its high wear resistance, high hardness, and excellent durability, the boron-carbide sandblasting device will eventually replace existing cemented caride/tungsten steel, silicon carbide, silica nitride and aluminum oxide sandblasting devices. 5.other Boron carbide may also be used for the production of metal borides as well as smelting sodium, boron alloys and special welding. Biomedicalmaterialsprogram has over 12 years' experience in Boron carbide research and development. We are here to help you find high-quality Boron carbide.

Gallium Telluride with Strong Anisotropic Resistance in Two-dimensional Limit

The Current Situation of Conductive Aisotropy within Two-dimensional Limit Lattice symmetry can influence the thermal conductivity of crystal materials. The conductivity, conductivity, Raman number, and other physical quantities are affected by inherent anisotropy. The conductivity of ab in graphite, for example, is three orders larger than that outside in the C direction. This is also true in three-dimensional block van der Waals materials. New phenomena such as anisotropy on various surfaces have been emerging in recent years with the rapid development of two-dimensional material research. The Raman anisotropy phenomenon and the in-conductivity anisotropy two-dimensional van der Waals material with low latticesymmetry (such SnSe or GeP) are just a few of them. This area has been receiving more research and attention. The prototype devices that are based upon this should be quickly designed and built. However, current anisotropy data in the two-dimensional limit are within 10 which makes them unsuitable for the design and development of new devices. However, it is difficult to know if electrical anisotropy could be controlled using quick and simple means.

The Two-dimensional Limiting Sublayer Semiconductor Material Galium Telluride

Researchers from the Chinese Academy of Sciences, Shenyang National Research Center for Materials Science, the Chinese Academy of Sciences, the Chinese Academy of Sciences, the Chinese Academy of Sciences, the Chinese Academy of Sciences, the Chinese Academy of Sciences, the researchers discovered two dimensions in the lower limit semiconductor . These measurements were made under the regulation of the electrical anisotropy of several orders of magnitudes. Finally, the relevant prototype was demonstrated.

The Effects Of Gallium Telluride

Vertical assembly of atomic layers within an inert atmosphere allowed the team to contain a few layers each of gallium-telluride (between 4.8 and 20.0 nm) in two layers each of boron nutride. Micro- and nano-processing was used to prepare the field effect devices. Electrical measurements were systematically carried out. Experimental results showed that conductivity in a few layers containing holes of gallium Telluride at room temperatures shows an elliptic behavior, with the direction changing. The conductivity anisotropy of these systems is comparable to SnSe or GeP. You can increase the conductivity anisotropy by controlling the gate voltage. It is much higher than the other systems that have in-plane electro anisotropy. Biomedicalmaterialsprogram (aka. Advanced material by Biomedicalmaterialsprogram .

Metal Alloy

Scandium Aluminum Alloy Al-Sc Alloy

About Scandium Aluminum Alloy Al-Sc Alloy:
Al-Sc alloy is a kind of high-performance aluminum alloy. There are several ways to make an aluminum alloy with high performance. Microalloying hardening and toughening is the frontier field of research on high-performance aluminum alloy in recent 20 years. Scandium aluminum alloy is a successful combination of scandium and aluminum metal. Scandium is a silvery-white transition metal and is commonly listed as a rare earth element (REE) along with yttrium (Y) and the 15 lanthanides (La) elements. The alloying of scandium into an aluminum can increase the strength and desirable properties of aluminum. The addition of scandium restricts the excessive growth of grains in the heat-affected zone of aluminum welds. Biomedicalmaterialsprogram is a trusted global Scandium Aluminum Alloy Al-Sc Alloy supplier. Feel free to send an inquiry about the latest price of Al-Sc Alloy at any time.

Product Performance of Scandium Aluminum Alloy Al-Sc Alloy :

Aluminum scandium intermediate alloy is a high-performance aluminum alloy, which can not only significantly refine the as-cast alloy grains, increase the recrystallization temperature to improve the strength and toughness of the aluminum alloy, but also significantly improve the weldability and resistance of the aluminum alloy Thermal, corrosion resistance, thermal stability and resistance to neutron radiation damage.

How is Scandium Aluminum Alloy Al-Sc Alloy Produced?
The preparation of the master alloy is the key to the production of Al-Sc alloy. The preparation method is as follows:
Preparation of anhydrous scandium chloride molten salt
1. Vacuum dehydration
Dissolve SC2O3 in hydrochloric acid, and mix SC2O3: NaCl: KCl: NH4Cl in proportion. Evaporation, vacuum removal.
2.Dehydrate at medium temperature
The molten salt after vacuum dehydration is heated under the protection of argon to make molten salt of ScCl3·NaCl·KCl, namely, anhydrous scandium chloride.
Preparation of Al-Mg-Sc master alloy
Industrial pure aluminum and industrial pure magnesium, ampere proportional heating melting. Adding SCCl3 ·NaCl·KCl molten salt, and specific additives, smelting, casting, aluminum, magnesium and scandium master alloy.

Applications of Scandium Aluminum Alloy Al-Sc Alloy:
Scandium aluminum alloys are used in small aerospace industry components. The common scandium content is 2%. The addition of scandium restricts the excessive growth of grains in the heat-affected zone of aluminum welds. Scandium can significantly increase the strength and decrease the grain size. The SC-Al alloy is also used in some sports equipment, including baseball bats, lacrosse sticks, and bicycle frames and related parts.
Aluminum can be made stronger by adding scandium
Scandium aluminum alloy has better welding property
The grain structure remains intact during the forming and extrusion process
When combined with zirconium, it increases with temperature.
Adding a small amount of scandium to the aluminum alloy can promote grain refinement and increase the recrystallization temperature from 250℃ to 280℃. Scandium is a strong grain refiner of aluminum alloy and an effective recrystallization inhibitor. It has a significant effect on the microstructure and properties of the alloy, and greatly improves the strength, hardness, weldability and corrosion resistance of the alloy.
Scandium has a good dispersive strengthening effect on aluminum and maintains a stable non-recrystallized structure under hot working or annealing conditions.
The inhibition effect of scandium on recrystallization can eliminate the recrystallization structure in the heat-affected zone of the weld. The subcrystalline structure of the matrix can be transferred directly to the as-cast structure of the weld seam, which makes the welded joint of an aluminum alloy containing scandium have higher strength and corrosion performance.
The effect of scandium on the corrosion resistance of the aluminum alloy is also related to the refinement of grain and the inhibition of the recrystallization process. The addition of scandium can also make the aluminum alloy have good superplasticity. The elongation of an aluminum alloy containing about 0.5% scandium can reach 1100% after superplastic treatment.
An aluminum alloy containing scandium has become the most competitive high-performance aluminum alloy structure material after Al-Li alloy. The application prospect of scandium aluminum alloy in shipbuilding, aerospace, rocket missile, nuclear energy and other high-tech fields is very broad. By adding a small amount of scandium, a series of new high-performance aluminum alloy materials, such as ultra-high strength and high toughness aluminum alloy and high strength and corrosion-resistant aluminum alloy, can be developed on the basis of the existing aluminum alloy.

Storage Condition of Scandium Aluminum Alloy Al-Sc Alloy :
The damp reunion will affect Al-Sc alloy dispersion performance and using effects, therefore, scandium aluminum alloy should be sealed in vacuum packing and stored in a cool and dry room, the scandium aluminum alloy can not be exposure to air. In addition, the Al-Sc alloy should be avoided under stress.

Oxide Powder

Silicon Dioxide SiO2 powder CAS 7631-86-9

About Silicon Dioxide SiO2 powder:
Silica, also known as silicon dioxide, is a silicon oxide with the chemical formula SiO2. The most common form in nature is quartz and various organisms. In many parts of the world, silica is the main component of sand. Silica is one of the most complex and abundant material families, in the form of mixtures of various minerals and synthetic products. Notable examples include fused silica, fumed silica, silica gel and aerogel. It is used in structural materials, microelectronics (as electrical insulators), and components in the food and pharmaceutical industries.

Inhalation of finely divided crystalline silica is toxic and can cause severe inflammation of lung tissue, silicosis, bronchitis, lung cancer and systemic autoimmune diseases such as lupus and rheumatoid arthritis. High-dose inhalation of amorphous silica can cause non-permanent short-term inflammation, and all effects can be cured.

Long-range arrangement of silicon and oxygen atoms forms crystalline silica, short-range arrangement or long-range disordered arrangement forms amorphous silica. In a silicon dioxide crystal, the silicon atoms are at the center of a regular tetrahedron, and the four oxygen atoms are at the four corners of the tetrahedron. Many tetrahedrons are held together by oxygen atoms at the four corners. Each oxygen atom is shared by two tetrahedrons, that is, each oxygen atom is bonded to two silicon atoms.

The simplest molecular formula for silica is SiO2, but SiO2 does not represent a simple molecule (just the ratio of the number of silicon atoms to the number of oxygen atoms in the crystal of silica). Pure natural silica crystal is a hard, fragile, insoluble, colorless and transparent solid, often used in the manufacture of optical instruments.

How is Silicon Dioxide SiO2 powder produced?
Preparation method of amorphous silicon dioxide
The preparation of amorphous silica includes five steps, namely the preparation of silica gel, granulation process, sintering process, cleaning process and drying process.
1. Preparation of silica gel
Crushing silicon tetrachloride can produce silica gel, or pulverizing organic silicon compounds (such as tetra methoxy siloxane) to produce silica gel, or using fumed silica can produce high-quality silica gel.
2. Granulation process
By drying the silicone gel into a dry powder, pulverizing the dry powder, and then performing classification, a silica powder with a desired average yield can be obtained.
3. Sintering process
The silica powder obtained in the granulation process is sintered at a temperature of 800°C to 1450°C. The spheroidization process of thermal plasma is used to introduce argon gas at a predetermined flow rate and convert the output at a predetermined frequency to generate plasma. In the plasma torch, the sintered and obtained silica powder is dispersed at a predetermined feed rate, and heated and melted at a temperature of 2000 ℃ to the boiling point of silica.
4. Cleaning process
After the spheroidization step, the fine powder adhering to the surface of the spheroidized silica powder is removed.
5. Drying process
After the above cleaning process, the silica powder is dried.

Applications of Silicon Dioxide SiO2 powder:
Silica is a raw material for manufacturing glass, quartz glass, water glass, optical fiber, important parts of the electronics industry, optical instruments, handicrafts and refractory materials, and important material for scientific research.

1. Silica is the main ingredient in most glass production. When other minerals melt with silica, the freezing point reduction principle reduces the melting point of the mixture and increases the fluidity. The glass transition temperature of pure SiO 2 is about 1475K. When fused silica SiO2 cools quickly, it will not crystallize but will solidify into the glass. Therefore, most ceramic glazes are mainly composed of silica.
2. Silica can also be used as an additive, an excellent flow promoter, mainly used as a pressurizing agent, anti-sticking agent, and glidant.
3. Silica is particularly suitable for the granulation of oils and extracts, and it can also use glidants in direct compression.
4. As a disintegrant, silicon dioxide can greatly improve the fluidity of the granules, increase the bulk density, and increase the hardness of the prepared tablets. It can be used as an internal desiccant in the manufacture of granules to enhance the stability of the drug.
5. Silica can also be used as a filter aid, scavenger, defoamer, suspending agent and thickener for liquid preparations.
6. About 95% of the commercial uses of silica (sand) occur in the construction industry, such as the production of concrete (Portland cement concrete).
7. In cosmetics, silica plays a certain role due to its light diffusion properties and natural absorption.
8. The process of passivating the silicon surface by thermal oxidation (silicon dioxide) is critical to the semiconductor industry. It is usually used to manufacture metal oxide semiconductor field-effect transistors (MOSFET) and silicon integrated circuit chips (using planar technology).
9. Silica can be used for the extraction of DNA and RNA because it can bind to nucleic acids in the presence of chaotropic agents.
10. Since silicon dioxide is a natural oxide of silicon, compared with other semiconductors such as gallium arsenide or indium phosphide, silicon dioxide is more widely used.
11. Silicon dioxide can be grown on the surface of silicon semiconductors. The silicon oxide layer can protect the silicon surface during the diffusion process and can be used as a diffusion mask.
