Hafnium Carbide Powder Description
Hafnium carbide (HfC) is a compound made of hafnium and carbon, renowned for its extreme refractory properties and melting point of approximately 3900 °C, making it one of the most heat-resistant binary compounds. It serves as a crucial raw material for CVD, fuel cells, solar energy applications, and sputtering targets.
Hafnium carbide is produced through the reaction of hafnium oxide and carbon at elevated temperatures, typically between 1800 and 2000 °C. The resulting powder exhibits a high modulus of elasticity, excellent electrical and thermal conductivity, and a low coefficient of thermal expansion, making it an exceptional choice for high-performance and high-temperature applications.
