Covalent Carbides Structure and Composition

As mentioned in Ch. 2, the refractory carbides include two structurally different types (a) the interstitial carbides of the transition metals of Group IV, V, and VI (reviewed in Ch. 3, 4, 5, and 6), and (b) two covalent carbides boron carbide and silicon carbide. The structural characteristics of these two carbides are reviewed in this chapter and their properties and general characteristics in the following chapter. 

The two covalent carbides have these general features  

They are both important industrial materials with many current and potential applications
