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.

Overview of tungsten carbide WC powder

Tungsten carbide is a compound composed of tungsten and carbon, with a molecular formula of WC and a molecular weight of 195.85. The most basic form of tungsten carbide is a fine gray powder, but it can be pressed into shape through a process called sintering, used in industrial machinery, cutting tools, abrasives, armor-piercing bullets and jewelry.

The stiffness of tungsten carbide is about twice that of steel, and the Young's modulus is about 530-700 GPa (77,000 to 102,000 ksi), which is twice the density of steel, almost between lead and gold. Its hardness is comparable to that of corundum (α-Al2O3), and only cubic boron nitride and diamond powder, grinding wheels and compounds with high hardness abrasives can be used for polishing and finishing.

Tungsten carbide is a black hexagonal crystal with a metallic luster and hardness similar to diamonds. 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, if a small amount of titanium, cobalt and other metals are added, its brittleness can be reduced. Tungsten carbide used as steel cutting tools is usually 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 as a material for cemented carbide production.

Application of tungsten carbide WC powder

Tungsten carbide is widely used as high-speed cutting tools, furnace structure materials, jet engine parts, cermet materials, resistance heating elements, etc. for manufacturing cutting tools, wear-resistant parts, and melting crucibles for metals such as copper, cobalt and bismuth, And wear-resistant semiconductor film.

Tungsten carbide is used as superhard tool material and wear-resistant material.

Tungsten carbide can form a solid solution with many carbides. WC-TiC-Co carbide tools have been widely used.

Tungsten carbide can also be used as a modified additive for NbC-C and TaC-C ternary carbides, which can reduce the sintering temperature and maintain excellent performance. It can be used as aerospace material.

Tungsten carbide (WC) powder can also be synthesized by using tungstic anhydride (WO 3) and graphite in a reducing atmosphere at a high temperature of 1400 ~ 1600°C. Dense ceramic products can be obtained by hot pressing sintering or hot isostatic pressing sintering.

Tungsten carbide (WC) powder can also be used to produce high-performance nanocrystalline or ultra-fine keratin alloys, hard-surface wear-resistant spraying and petrochemical cracking catalysts; chipless molding tools; cutting tools; mining fees; nanocomposites (used to enhance hardness, Strength and wear resistance); corrosion-resistant coatings; wear-resistant coatings; corrosion-resistant coatings; wear-resistant parts.
