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. [4]

Tantalum hafnium carbide - Wikipedia

Very few measurements of melting point in tantalum hafnium carbide have been reported, because of the obvious experimental difficulties at extreme temperatures. A 1965 study of the TaC-HfC solid solutions at temperatures 2225–2275 °C found a minimum in the vaporization rate and thus maximum in the thermal stability for Ta 4 HfC 5.
