Hafnium Boride

Hafnium Boride Description

Hafnium boride (or hafnium diboride) is a unique high-temperature ceramic material with excellent thermal and electrical conductivity. It is an unusual ceramic, having relatively high thermal and electrical conductivity.

Hafnium boride is a light gray, metallic-looking material. The oxidation resistance of hafnium boride is dependent on the temperature and pressure. At a temperature of 1500°C and 1 atm of pressure, a protective oxide scale of hafnia forms. When temperatures rise above 1600°C and pressures drop below 1 atm, the oxidation resistance of HfB2 is dramatically reduced.

Hafnium boride powder has the potential for use in hypervelocity reentry vehicles such as ICBM heat shields or aerodynamic leading-edges, due to its strength and thermal properties. Unlike polymer and composite material, HfB2 can be formed into aerodynamic shapes that will not ablate during reentry.

Hafnium boride is also investigated as a possible new material for nuclear reactor control rods. It is also being investigated as a microchip diffusion barrier. If synthesized correctly, the barrier can be less than 7 nm thick.
