TUNGSTEN CARBIDE Chemical Properties,Usage,Production

Chemical Properties black hexagonal, a=0.29982 nm, c=0.4722nm; can be prepared by heating tungsten and carbon in the presence of hydrogen at high temperatures; hardness approaches that of diamond; brittle; used in hard metals, and as a 99.5% pure sputtering target to produce wear-resistant films and semiconductor films [KIR83] [CIC73] [CER91] [CRC10]
Physical properties Black. Resistant to oxidation in air up to 700°C. Corrosion resistant to Mo.
Uses Tungsten carbide is used in industrial machinery, cutting tools, abrasives, armor-piercing rounds and jewelry. It is preferred even over stainless steel because of their incredible hardness and resistance to wear and tear. It is utilized for the manufacture of mill products including grinding and milling. It also includes tipping trekking, ski poles as well as cleats. It is mainly used in the form of cemented tungsten carbide.
Uses Tungsten Carbide/Carbon (WC/C) is a black-gray colored coating of hard tungsten carbide particles in a soft amorphous carbon matrix. It is used for precision components with abrasive and adhesive wear, seizure problems (poor lubrication) and for dry machining applications.
Definition Either of two carbides (W₂C and WC) produced by heating powdered tungsten with carbon. The carbides are extremely hard and are used in industry to make cutting tools or as an abrasive. WC has a very high melting point (2770°C) and will conduct electricity. W₂C also has a very high melting point (2780°C) but is a less efficient conductor of electricity. It is very resistant to chemical attack and behaves in a manner very similar to that of tungsten. It is strongly attacked by chlorine to give tungsten hexachloride, WCl₆.
