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. Hafnium carbide is usually carbon deficient and therefore its composition is often expressed as HfCx (x = 0.5 to 1.0). It has a cubic (rock-salt) crystal structure at any value of x.

Material Notes

Hafnium Carbide Sputtering Target, Purity is 99.5%; Circular: Diameter <= 14inch, Thickness >= 1mm; Block: Length <= 32inch, Width <= 12inch, Thickness >= 1mm. Bonding is recommended for these materials. Many materials have characteristics which are not amenable to sputtering, such as, brittleness and low thermal conductivity.This material may require special ramp up and ramp down procedures. This process may not be necessary with other materials. Targets that have a low thermal conductivity are susceptible to thermal shock.
