    Hafnium

    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. [19] This has led to proposals that hafnium or its carbides might be useful as construction materials that are subjected to very high temperatures.

    Synthesis and characterization of hafnium carbide fine ...

    A carbothermal method was used to produce hafnium carbide from HfCl 4 and citric acid. Hafnium carbide formation started at 1000 °C. The comparatively low reaction temperature is attributed to an intimate, atomic level, mixing of Hf and carbon which is achieved by gelation of water solution of the precursors. Increase in temperature resulted in an increase in volume fraction of formed hafnium carbide.
