The chemical properties of hafnium carbide


Hafnium carbide
has the following chemical properties :Chemical formula is HfC, relative atomic weight is 190.5, the theoretical content of carbon is 6.30% with high chemical stability and good high temperature properties. Melting point is 3890 ℃, belonging to a highest bidder in single compound of melting points as we known . Volume resistivity is 1.95 × 10-4Ω · cm (2900 ℃), usually hafnium oxide (HfO2) and carbon composite powder in an inert or reducing atmosphere, the reaction temperature is 1900 ~ 2300 ℃, hafnium carbide with some metal carbides : hafnium carbide ZrC, tantalum carbide TaC, etc. form a solid solution. It has a high melting point and high elastic modulus, good electric conductivity, low thermal expansion and good impact properties. 4TaC HfC melting point is about 4215 ℃, the highest melting point compounds as we known.
