CAS 12069-85-1 Hafnium Carbide Powder HfC Powder Price
Product name: HfC Powder Price Hafnium Carbide Powder
Description of HfC Powder
Hafnium carbide (HfC Powder) is a compound of carbon and hafnium. Its melting point is about 3900°C, which is one of the most refractory binary compounds known. However, its oxidation resistance is very low, and oxidation starts at temperatures as low as 430°C.
HfC powder is a black, gray, brittle solid; high cross-section absorbs thermal neutrons; resistivity 8.8μohm·cm; the most refractory binary material known; hardness 2300kgf/mm2; used in nuclear reactor control rods; It is prepared by heating HfO2 with oil soot under H2 at 1900°C-2300°C. It is used in the form of the crucible to melt oxide and other oxides.
