Hafnium - Wikipedia

Hafnium carbide is the most refractory binary compound known, with a melting point over 3890 °C, and hafnium nitride is the most refractory of all known metal nitrides, with a melting point of 3310 °C. This has led to proposals that hafnium or its carbides might be useful as construction materials that are subjected to very high temperatures.

Hafnium(IV) carbide - Wikipedia

Hafnium carbide (Hf C) is a chemical compound of hafnium and carbon.With a melting point of about 3900 °C it is one of the most refractory binary compounds known. However, it has a low oxidation resistance, with the oxidation starting at temperatures as low as 430 °C. This compound will be soon be seen on future spacecrafts functioning as heat-resistant shields.
