Hafnium Diboride HfB2 Powder CAS 12007-23-7

What are the uses for Hafnium Diboride Powder
Hafnium Diboride in wear-resistant coats Because of its exceptional fire resistance, it can also be used in ultra high temperature composite materials (SiC) with silicon carbide. This material is more resistant to oxidation when it has been combined with silicon carbide.
Temperature and pressure determine the resistance to oxidation of hafnium-diboride. At 1500 degrees Celsius and 1 atmosphere pressure, a protective oxide of hafniumoxide is formed. HfB2’s oxidation resistance will decrease significantly if it is heated above 1600 degrees Celsius and the pressure is below 1 atmosphere. These conditions will cause the boiling temperature for B2O3 (another oxidation product of HfB2) to exceed 1400°C. A protective oxide layer will then form.
Because of its strength and thermal characteristics, HfB2 can be used in ultra high-speed reentry vehicle, such as heat shields, for intercontinental ballistic missiles, or aerodynamic fronts. HfB2 forms aerodynamic shapes unlike composite and polymers, and does not ablate during reentry.
Hafnium Diboride has been also investigated as a possibility for new materials in nuclear reactor control rods.
