A carbide is a compound inwhich carbon has a negative oxidation state compared with more positive (metallic) elements. Several carbides exist such as boron carbide which is used as an abrasive. One active carbide is calcium carbide which will produce acetylene gas when combined with water.

A carbide is a compound of carbon in which the oxidation number of carbon is -3. There are only two true carbides, beryllium carbide, Be2C, and aluminum carbide, Al4C3. Other metal carbides are actually acetylides, compounds of C2=, where C2= is -C*triplebond*C-. Silicon carbide is a covalently bonded, three-dimensional compound, which doesn't count.
