How about the tungsten alloy made of tungsten powder?

What's tungsten powder? Tungsten powder Reduced with hydrogen in either a four tube muffle furnace (using tungsten dioxide as the raw material) or multi-tube furnace (using tungstenoxide). It has a particle size of 0.6-30 microns. It can be divided into medium, fine and coarse particles. It is determined using the national standard for impurity. The impurity content is determined by the national standard. Preparing tungsten powder using hydrogen reduction generally involves two stages. In the first, there is a reduction in tungsten trioxide into tungsten dioxide at 500700oC. In the second stage, tungsten bioxide is reduced to powder at 700900oC. The reduction reaction takes place in either a tubular electric or rotary furnace. It is important to know the performance characteristics of the reduced powder tungsten (e.g., purity, composition and size). It all depends on how the reduction is done. Tubular furnaces can reduce tungsten to a powder. The process parameters that determine the reduction rate include the reduction temperature, volume of tungsten dioxide in the burned boat, burning boat speed, flow rate of hydrogen, and moisture in hydrogen. As the temperature decreases, the tungsten powder's particle size becomes larger.

Standard properties of tungsten-powder
The oxygen content in tungsten powder should not exceed a specified limit. There are also certain specifications regarding the impurity level. The common tungsten particle size is 210 times that of the Fisher size m.m. Most tungsten particles are polygonal in shape. The specific surface area of the tungsten powder, its bulk density and tap density can all vary. These properties have a direct impact on the production of high-quality tungsten powder and their quality. Tungsten powder has three types: purity, size and uses. In the beginning, tungsten-reduced tungsten slurry was divided into three grades. Japan established the JISH2116-1979 industrial standard for Tungsten Powder. France, Britain and many other countries have their own unified national standards. For tungsten powder manufactured in China, Technical Conditions for Hydrogen Reduction (GB3458-82) has been formulated. This standard sets out the classification grades and properties of tungsten powder. The standard specifies inspection methods and acceptance rules. It also includes instructions for transportation, storage, transport, and packaging. You can request tungsten powder to be made according to your requirements.

Use of tungsten powder
Processing powder metallurgy items and tungsten alloys begins with tungsten powder. You can make wires and tubes from pure tungsten powder. Mixed tungsten powder can make a number of different tungsten alloys. These include tungsten rhenium and tungsten copper, as well as high-density tungsten. The tungsten-powder can also be used in making tungsten carbide powder. This is useful for turning tools, drilling tools, and other tools that use cemented carbide such as milling cutters.

The price of tungsten dust
Price will depend on how finely tungsten powder is made. The purchase volume may also have an effect on price. Large quantities of small amounts will result in a lower price. On our official website, you can see the cost of tungsten powder.

Facts About Actinium

Actinium is a member of the actinide series of elements. It is a rare element. In fact, it is one of the first non-primordial radioactive elements to be isolated.

Actinium is a member of group three on the periodic table. This group includes fifteen chemical elements. Several of them are synthetic, but the rest are naturally occurring.

Actinium is considered to be the first of the actinides. The actinides are characterized by a gradual filling of the 5f subshell.

Because of its physical and chemical properties, it closely resembles lanthanum. However, it differs in the ionic radii of its isotopes. For instance, its valence electrons are only three.

Actinium is produced in a variety of ways. Most commonly, it is obtained by neutron irradiation of the radium isotope 226Ra in a nuclear reactor. However, it is also a precursor to other radioactive isotopes. Some of its applications include a neutron source, and a radiation therapy agent.

Actinium is an attractive candidate for future radioisotope thermoelectric generators. It has an atomic radius of 195 pm. It emits alpha rays and glows when it is irradiated. When it is in gaseous form, it does not have any 5f electrons.

Actinium is an element that is found in nature. A trace amount of it is found in uranium ore. One tonne of uranium ore contains 0.2 milligrams of the isotope 227Ac.

The atomic radius of actinium is 195 pm. It has 89 protons and 138 neutrons.

Aluminum Scandium Alloys

Aluminum Scandium alloys are designed to improve strength, thermal stability and corrosion resistance. They are primarily used in aerospace and industrial applications. For example, they are used in aircraft, missiles and aircraft components.

In addition, aluminium-scandium alloys are used in sports equipment, such as lacrosse sticks, baseball bats and bicycle frames. The alloy is also used in fuel cells, micro-electro-mechanical systems (MEMS) and lasers. These applications have increased demand, as do new applications such as light-weight high-strength aluminum alloys.

Research into scandium-containing aluminum has shown improved physical properties at higher temperatures. However, this new alloy has limitations. It is expensive and has been found to be relatively difficult to manufacture. Therefore, an improved process is needed. This is why Rio Tinto and metal additive manufacturing specialist Amaero have teamed up.

Rio Tinto will supply the first commercial batch of the high-performance alloy to Amaero. They will also work together to develop a supply chain for the alloy.

During production, a molten salt mixture of alumina and aluminum oxide is heated to a temperature of about 600°C. Throughout the production cycle, the concentration of scandium oxide is maintained at between 2 and 8 wt. %.

When the aluminum-scandium alloy is cooled, it possesses the properties of a superplastic aluminum. In cold rolling, the alloy demonstrates increased tensile strengths. Another advantage of the alloy is its higher strength when exposed to high temperatures.

The physical properties of the aluminum-scandium alloy are enhanced by selective aging treatments. The temperature and duration of the aging treatment are chosen to provide the desired effect.

Development History and Application of Colloidal Gold

Colloidal Gold development history It is possible to trace the origins of gold nanoparticles back to the 16th Century. nanogold emerged from the scientific community after Paracelsus invented "drinking golden" for mental disorders. Faraday studied Dalton's theory and used gold chloride in 1857 to reduce the solution. He also discovered that adding electrolytes can make it turn from red color to blue, then finally to colorless. Edward et.al. from Chicago discovered that the nano-gold solution was effective in relieving patients of their diseases and strengthening their bodies. Faulk combined rabbit anti-salmonella and nano-gold antiserum in immunogold staining, which was the first to use this combination. This technology led to nano-gold immunolabeling technology.

Colloidal Gold

1.Gold nuparticles may be used in the detection of cancer

Sciencedaily stated that nanoparticles of gold can be used to detect early cancers such as the mouth, neck, and brain. Injecting nanogold into a patient can make cancer cells stick to the body and reflect certain wavelengths of light. 2.Gold nanoparticles may be used in chemotherapy for cancer Both normal and immune cells can be damaged by conventional chemotherapy. Xinhuanet.com stated that gold nanoparticles could improve chemotherapy’s effect and minimize side effects. The gold nanoparticles have a high absorption rate and can therefore be coated with chemotherapy drugs to be delivered directly to the cancer cells. You can heat nanogold that has been infrared heated to kill cancer cells. This means that chemotherapy with nanogold may be effective in killing cancer cells, without affecting normal cells. It is possible to make an injection out of nanogold These USES can be combined with nano-gold injections. Chinanews.com has reported that nano-gold can be used to balance the electrolyte level of the cells. It also improves the immunity. It is small and will reach the cells quickly because it's easily absorbed by the body. You can use it to restore immune system, reduce inflammation, pain, nerve pain, and improve blood circulation.

Sulfide Powder

Tungsten Disulfide WS2 Powder CAS 12138-09-9

About Tungsten Disulfide WS2:
Tungsten disulfide is an inorganic compound composed of tungsten and sulfur, with the chemical formula WS2. This compound is part of a group of materials called transition metal dihalides. It naturally appears as a rare tungsten ore. This material is part of certain catalysts used for hydrodesulfurization and hydrodenitrogenation.
WS2 uses a layered structure similar to MoS2 or the same type of MoS2, instead of a coordination sphere with W atoms (instead of molybdenum atoms) in a triangular prism. Due to this layered structure, WS2 formed inorganic nanotubes, which were discovered after heating a thin sample of WS2 in 1992.
Most of the WS2 forms dark gray hexagonal crystals with a layered structure. Like the closely related MoS2, it has the characteristics of a dry lubricant.
Although people have long believed that WS2 is relatively stable in ambient air, recent reports on single-layer WS2 oxidation in the environment have found that this is not the case. WS2 is converted to tungsten oxide in a single layer form by a photooxidation reaction fairly quickly (within a few days in ambient light and atmosphere). The oxidation process includes visible wavelength light easily absorbed by the single-layer WS2 (
WS2 is also attacked by a mixture of nitric acid and hydrofluoric acid. When heated in an oxygen-containing atmosphere, WS2 is converted to tungsten trioxide. When heated in the absence of oxygen, WS2 will not melt but will decompose into tungsten and sulfur, but the decomposition temperature is only 1250°C.
Historically, the separation of monolayer WS2 used a chemical exfoliation method, that is, inserting lithium from n-butyl lithium (in hexane), and then stripping the inserted Li compound by ultrasonic treatment in water. WS2 is also shed by treatment with various reagents such as chlorosulfonic acid and lithium halide. Feel free to send an inquiry to get the latest price if you would like to buy tungsten disulfide WS2 powder in bulk.

Tungsten Disulfide details:
Tungsten Disulfide particle size: FSSS=0.4 to 0.7 μm, FSSS=0.85 to 1.15μm. 80nm
Tungsten Disulfide purity: 99.9%

W	S	Al	As	Cl	Cu	Fe	Ni	P	Si	O
74.12	25.82	0.001	0.002	0.03	0.002	0.005	0.002	0.002	0.003	0.002

How is Tungsten Disulfide WS2 produced?
1. Roasting decomposition method:
Tungstic acid reacts with ammonia water under stirring at 57-60°C for 3 hours, and the heat preservation naturally settles for more than 16 hours. The generated ammonium tungstate reacts with hydrogen sulfide gas to generate ammonium tetrathiotungstate after high-temperature roasting and decomposition into tungsten disulfide.
H2WO4+2NH3·H2O→(NH4)2WO4+2H2O
(NH4)2WO4+4H2S→(NH4)2WS4+4H2O
2(NH4)2WS4+3O2→2WS2+4NH3+2S+2SO2+H2O
2. Tungsten reacts very slowly with liquid sulfur. WS2 can be formed by passing sulfur vapor to red hot tungsten. Tungsten is mixed with stoichiometric sulfur bloom and reacted in a nitrogen atmosphere at 800°C for 24 hours to form WS2, such as reacting at 6MPa and 1800°C to form orthorhombic WS2.
3. Using ammonium tetrathiotungstate as the raw material, heating and decomposing the ammonium tetrathiotungstate under the condition of isolating the air, the temperature rises from room temperature to 700-1200℃ with a temperature gradient of 100-200℃/hour during heating. After being kept at this temperature for 24 to 48 hours, it is then reduced to room temperature with a temperature gradient of 30 to 110°C/hour, and the material is discharged and crushed.
The preparation method of ultrafine scaly crystal tungsten disulfide used for lubricants has simple process equipment, does not pollute the environment, and is safe and reliable in operation, and can produce tungsten disulfide with stable quality, high purity, and ultrafine crystal structure of hexagonal crystal system.

Applications of Tungsten Disulfide WS2:
Tungsten disulfide (WS2) or tungsten disulfide is a very smooth dry film friction coating. The friction coefficient of WS2 is extremely low, 0.03, which is lower than PTFE, graphite or molybdenum disulfide (MoS2). Compared with many other WS2, it has unparalleled performance in terms of lubricity, non-stick, low friction, wears life and rated size. It has a wide range of applications in transistors, sensors, photocatalysis, electronic equipment, etc. Tungsten disulfide powder has good solubility in water and ethanol.
WS2 is an excellent release material for plastic molds, extrusion molds and other demolding applications.
WS2 can eliminate the need for hydraulic oil, or can be used with petrochemical oil, grease, synthetic oil, silicone valve and hydraulic oil. It has an affinity for the fluid layer and maintains the fluid layer. It helps to keep oil or grease on the surface, thereby further improving the lubrication effect.
When the thickness is less than 1 micron, small parts can be coated without tolerance problems.
WS2 is also a fairly inert and non-toxic material that has been used in medical equipment and food processing applications.
WS2 replaces customer base materials through high-speed processes at ambient temperature. It does not make the substrate continuous or warped.
WS2 can be used alone or combined with our PVD hard coating to improve durability.

Storage Condition of Tungsten Disulfide WS2 Powder:
Damp reunion will affect WS2 powder dispersion performance and using effects, therefore, Tungsten Disulfide WS2 Powder should be sealed in vacuum packing and stored in cool and dry room, the Tungsten Disulfide WS2 Powder can not be exposure to air. In addition, the WS2 powder should be avoided under stress.
