calcium carbide hardness

Calcium Carbide an overview ScienceDirect Topics

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).
