karbidien
Karbidien are chemical compounds consisting of carbon combined with elements other than carbon, typically metals. They are commonly called carbides and encompass a range of structures, from binary inorganic carbides to covalent ceramic networks.
Two broad groups are recognized: inorganic binary carbides formed between carbon and metals (for example CaC2,
Carbides are typically prepared by carbothermic reduction, reacting metal oxides with carbon at high temperature, or
Carbides generally possess high melting points, high hardness, and chemical stability. They find use in cutting
Natural occurrences of carbides are rare; moissanite is a natural silicon carbide mineral. Most carbides are
