Hafnium (IV) Carbide (HfC)

Hafnium (IV) carbide is a dark, gray, brittle solid that has high hardness and a very high melting point of over 3890°C. It is one of the most refractory binary compounds and is extremely hard. It has a high cross-section for the absorption of thermal neutrons.

Purity: 99.5%
Typical Applications

Hafnium carbide is used for extremely high-temperature applications such as rocket nozzles and scramjet components. Hafnium carbide is used in hard coatings, applied by plasma spraying. HfC is used in structural foams that can be fabricated into high-temperature components or thermal insulation material. It is used in ceramics and as a hard alloy additive. It has applications in the control rods and as refractory coatings of nuclear reactors.

Packaging Options

50 lb. bags, poly-lined fiber drums, and bulk bags
