Carbide, any of a class of chemical compounds in which carbon is coined with a metallic or semimetallic element. Calcium carbide is important chiefly as a source of acetylene and other chemicals, whereas the carbides of silicon, tungsten, and several other elements are valued for their physical hardness, strength, and resistance to chemical attack even at very high temperatures.
Boron Carbide (B4C) is one of the hardest materials known to man. As such, many of its appliions revolve around its wear resistance including such uses as abrasives and nozzles. It also has some interesting and very useful nuclear properties which are used in
Wheel and Belt Grease (Polishing Lubricants) Kocour lubricants are designed for wheels and belts set with aluminum oxide, silicon carbide or turkish emery grain. Often used with second or third stage polishing operations to “oil out” prior to buffing.
