Hafnium Diboride (HfB₂)

Hafnium diboride is a gray, metallic-looking, ultrahigh-temperature ceramic composed of Hafnium and Boron. It has relatively high thermal and electrical conductivity and a melting temperature of about 3250ºC. The material’s oxidation resistance is temperature, and pressure dependent, where at 1500ºC and 1 atm of pressure, it shows resistance; however, at temperatures above 1600ºC and pressures drop below 1 atm, the oxidation resistance is dramatically reduced.

Purities available 99% to 99.99%
Chemical Composition

Hf= 89.195%
B= 10.804

Typical Applications

The material has potential for use in hypervelocity reentry vehicles, nuclear reactor control rods, and as a microchip diffusion barrier.

Packaging Options

Steel drums
