Covalent carbides are typified by silicon carbide and boron carbide, which are both important structural ceramics because of their high hardness and thermal stability. • Interstitial carbides form from the transition elements of groups 3a, 4a, 5a, and 6a. Group 3a carbides are important as precipitates in metallic alloys (iron, cobalt, nickel).
