Common Features of Group VI Carbides

This chapter is a review of the characteristics and properties of the interstitial carbides formed by the metals of Group VI chromium, molybdenum, and tungsten. These three carbide systems have similar atomic bonding, composition, and crystallography. Their properties and characteristics are also similar. 

They have a more complex composition and crystallography than the carbides of Groups IV and V. As shown in Ch. 3, their structural characteristics can be summarized as follows  

The carbides of Group VI are important industrial materials, particularly tungsten carbide and chromium carbide. Their fabrication processes and plications are summarized in Secs. 6, 7, and 8 and reviewed in more detail in Chs. 14, 15, and 16.
