Products such as pure silicon are made via the lely process, in which the carbon powder is sublimated in argon and then redeposited. types. examples of different types of carbides include boron carbide, silicon carbide, and tungsten carbide (wc). boron carbide (b 4 c) has higher hardness than alumina
Boron carbide is one of the hardest materials known, ranking third behind diamond and cubic boron nitride. boron carbide powder is mainly produced by reacting carbon with b2o3 in an electric arc furnace, through carbothermal reduction or by gas phase reactions.
