Hafnium Carbide is available in numerous forms and custom shapes including disc, granules, ingot, pellets, pieces, powder, rod, and sputtering target. High purity forms also include Carbide powder, submicron powder and nanoscale, single crystal or polycrystalline forms. Hafnium Carbide is generally immediately available in most volumes.
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.
Jan 08, 2004· The chemical formula for Hafnium Carbide is HfC. It is the most refractory binary compound known to man. Similarly, hafnium nitride (HfN) is the most refractory nitride known with a melting point of approximately 3305 °C ...
Physical Properties. Sintered pieces, targets, powder and fiber. HfC AVAILABILITY NEWS: Flowable HAFNIUM CARBIDE POWDER (99.5% min. and 45 microns x down) is regularly available as a by-product from our ongoing 200 X 325 mesh HfC production in Reno, Nevada.
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.
