Tungsten Carbide (WC) Micron Powder
Tungsten carbide (WC) is a chemical compound containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide powder is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering. Its melting point is approximately 2800℃ and has a density of 15.63 g/cm3. Tungsten carbide powders can be prepared by reaction of tungsten metal and carbon at 1400–2000 °C. Tungsten carbide is approximately twice as stiff as steel, with a Young's modulus of approximately 530–700 GPa. WC powders attract great interest for many structural applications due to its extremely high melting temperature, high hardness, high electrical conductivity. Therefore, titanium carbide can be used in cutting tools, grinding wheels, wear-resistant coatings, high temperature heat exchangers, magnetic recording heads, turbine engine seals, bullet-proof vests, abrasives, armor-piercing shells and jewellery.
