Hafnium(IV) carbide - Wikipedia

Hafnium carbide is usually carbon deficient and therefore its composition is often expressed as HfC x (x = 0.5 to 1.0). It has a cubic (rock-salt) crystal structure at any value of x. Hafnium carbide powder is obtained by the reduction of hafnium(IV) oxide with carbon at 1800 to 2000 °C. A long processing time is required to remove all oxygen.
