Tungsten carbide powder is mainly used in cemented carbide production materials

Overview of Tungsten Carbide WC Powder

Since 1893, German scientists have used tungsten trioxide and carbon to be heated to a high temperature in an electric furnace to produce tungsten carbide, and tried to use its high melting point and high hardness to produce wire drawing dies in order to replace diamond materials. . However, due to its brittleness, easy cracking and low toughness, tungsten carbide has not been used in industrial applications. In the 1920s, German scientist Karl Schroter discovered that pure tungsten carbide cannot adapt to the drastic stress changes formed in the drawing process. Only by adding low-melting metal to WC can the roughness be made without reducing the hardness. Has a certain degree of toughness. Schroter first proposed the method of powder metallurgy in 1923, that is, tungsten carbide is mixed with a small amount of iron group metals (iron, nickel, cobalt), then pressed into a shape and sintered in hydrogen at a temperature higher than 1300°C to produce a hardness alloy Patents.

Chemical nature

The active oxidation starts when the temperature is above 500℃ in the air, and the anti-oxidation ability is weak. Strong acid resistance.

Chemical reaction formula: W + C = WC Note: React at 1150℃.

It does not react with chlorine below 400°C; it can react violently with fluorine at room temperature; it is oxidized to tungsten oxide when heated in the air.

Tungsten carbide is a compound composed of tungsten and carbon, with a molecular formula of WC and a molecular weight of 195.85. It is a black hexagonal crystal with metallic luster and hardness similar to that of diamond. It is a good conductor of electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, but easily soluble in a mixed acid of nitric acid and hydrofluoric acid. Pure tungsten carbide is fragile, and if a small amount of titanium, cobalt and other metals are added, the brittleness can be reduced. Tungsten carbide used as a steel cutting tool is often added with titanium carbide, tantalum carbide or their mixture to improve the anti-knock ability. Tungsten carbide is chemically stable. Tungsten carbide powder is used in cemented carbide production materials.

Application of tungsten carbide WC powder

Tungsten carbide is widely used as high-speed cutting tools, furnace structural materials, jet engine parts, cermet materials, resistance heating elements, etc.

Tungsten carbide is used to manufacture cutting tools, wear-resistant parts, melting crucibles for metals such as copper, cobalt, and bismuth, and wear-resistant semiconductor films.

Tungsten carbide is used as super-hard tool material and wear-resistant material. It can form a solid solution with many carbides. WC-TiC-Co cemented carbide tools have been widely used. It can also be used as a modified additive of NbC-C and TaC-C ternary system carbides, which can reduce the sintering temperature and maintain excellent performance. It can be used as aerospace materials.

Tungsten carbide (WC) powder is synthesized by using tungsten anhydride (WO3) and graphite in a reducing atmosphere at a high temperature of 1400～1600℃. Dense ceramic products can be obtained by hot pressing sintering or hot isostatic pressing sintering.
