• 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.
• Uses: It is an ideal metal in the manufacture of control rods for nuclear reactors. Used for preparation of ultra-high temperature ceramics 1 Reactant in synthesis of hafnium-containing organometallic polymers 2 Additive in alloys 3 Used in coatings 4 Hafnium carbide (HfC) with a melting point over 3890°C is a refractory binary compound. HfC and NbC can also be used as refractory coatings in nuclear reactors. The mixed carbide Ta4HfC5 possesses the highest melting point of any currently known compound at 4215°C.
