Tungsten Carbide Powder
Chemical Formula：WC
Color：Dark Gray
Luster：Metallic luster
Relative Density：15.63g/cm3(18℃）
Shanghai Metal Corporation is a leading tungsten carbide powder supplier and manufacturer.
Tungsten carbide powder (WC) is the main raw material for the production of cemented carbide. Tungsten carbide powder is a black hexagonal crystal with metallic luster and hardness similar to diamond. It is a good conductor of electricity and heat. Pure tungsten carbide is fragile, 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.

-
1. Preparation of tungsten powder:
In the first stage, at a temperature of 500-700oC, tungsten trioxide is reduced to tungsten dioxide;
In the second stage, the tungsten dioxide is reduced to tungsten powder at a temperature of 700-900oC.
2. Use metal tungsten powder and carbon black as raw materials to prepare a mixture according to a certain ratio, and put the mixture into a graphite boat and place in a carbon tube.
3. In the furnace or in the high and medium frequency induction furnace, carbonization is carried out at a certain temperature, and then ball milled and sieved to obtain tungsten carbide powder.

Technical Information of Tungsten Carbide Powder:
Particle size, specific surface area, carbon and oxygen content
The Fibonacci average particle size, specific surface area, total carbon, free carbon, combined carbon, and oxygen content of tungsten carbide powder should meet the requirements. The appearance of tungsten carbide powder is gray, and the color changes from dark to light as the product size increases. The color should be uniform and there should be no visible inclusions.
