Carbide | chemical compound | Britannica

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.
