Hafnium Diboride Powder

Product	Hafnium Diboride Powder (HfB₂ Powder)
Part Number	HfB
CAS Number	12007-23-7

Hafnium diboride (HfB₂) is a gray, metallic crystal. Melting point is 3250°C. It has high conductivity and stable chemical properties.

Hafnium diboride (HfB₂) has excellent thermochemical stability, hardly reacts with all chemical reagents (except HF) at room temperature. It has excellent physical properties, including high elastic modulus, high hardness, low saturated vapor pressure, high thermal conductivity and conductivity, moderate thermal expansion and good thermal shock resistance. In addition, it can maintain high strength at high temperature, and thus is the most potential candidate material for ultra-high temperature ceramics. It is prepared by heating hafnium dioxide with boron carbide or boron oxide and carbon powder.
