Characteristic
Hafnium carbide (HfC) 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.
Chemical formula：HfC
Molar mass：190.50 g/mol
Appearance：black odorless powder
Density：12.2 g/cm3
Melting point：3,900 °C (7,050 °F; 4,170 K)
Solubility in water：insoluble
Crystal structure：Cubic crystal system, cF8
Application
Very suitable for rocket nozzles, which can be used as nose cones of re-entry space rockets. Used in ceramics and other industries.
