Why are tungsten powders widely used?
What is tungsten powder?
Tungsten powder is the main raw material for processing powder metallurgy products and tungsten alloys.Tungsten has a high melting point, a very low vapor pressure, and an evaporation rate. The chemical properties of tungsten are very stable, not reactive with air and water at room temperature, not heating, any concentration of hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid, and royal water do not work on tungsten when the temperature rises to 80° -100°C, the above acids, except hydrofluoric acid, other acids have a weak effect on tungsten.
Main uses of tungsten powder
Tungsten powder can be used as an analytical reagent; Tungsten powder is also used in the manufacture of hard or high-temperature resistant alloys, high-speed cutting special steel, and used as light bulb filament and heat resistant materials in the aviation and aerospace industries; Used for a large slab, tungsten - rhenium electric couple raw materials. FW-2 is used for contact alloy and high specific gravity shielding material. Used as plasma spray material; Used to make tungsten wire and high-speed cutting steel, special steel, also used to make electrical instruments and optical instruments. Used for ICP-AES, AAS, AFS, ICP-MS, ion chromatography, etc. Standard solution for titration analysis.
The production method of metallic tungsten powder
The main production methods of metal tungsten powder are hydrogen and carbon reduction. The main method of producing metal tungsten powder is the hydrogen reduction method of high-purity tungsten trioxide, blue tungsten oxide, and purple tungsten oxide. The carbon reduction method is mainly used to produce tungsten carbide. In addition, tungstate acid is also used for the hydrogen reduction method. The equipment for tungsten powder is usually a multitube furnace, rotary furnace, or tubular multi-bore furnace. A reduction furnace is usually provided with several heating areas. The tube through a total of hydrogen or ammonia flow tube, and the temperature is generally between 600℃ - 1200℃; to ensure fine tungsten powder, the gas into the tube will have excess gas through the hydrogen purification system recovery. It can be produced by reducing tungsten trioxide with hydrogen in industrial production. Or ammonium para tungstate with an acid treatment and then cooked decomposition to tungsten trioxide, with hydrogen reduction.
Price of tungsten powder
The different price of tungsten powder purity is also different. The market price of tungsten powder is in the process of dynamic change. The price of tungsten powder can be found on our company's official website. If you need it, you can ask us at any time.
