HAFNIUM CARBIDE Chemical Properties,Uses,Production

Description

Hafnium carbide (HfC) is a chemical compound of hafnium and carbon, which is one of the most refractory binary compounds known to man with a melting point of approximately 3900 ℃. Hafnium carbide powder is obtained by the reduction of hafnium oxide with carbon at 1800 to 2000℃, in which a long processing time is required to remove all oxygen. It possesses the highest melting point of any known binary alloy, because of which it has a variety of high-temperature applications. It is considered candidates for extremely high-temperature applications such as rocket nozzles and scramjet components. Hafnium carbide can also be used in hard coatings, often applied by processes such as plasma spraying. Besides, HfC structural foams can be fabricated into high temperature components or used as a thermal insulation material. It is also be used in ceramic industry.
