Hafnium Diboride Powder, HfB2

Product Code : ME-HfB2-5N-PO

Hafnium boride powder is an ultra-high temperature ceramic composed of hafnium and boron. It is an unusual ceramic, having relatively high thermal and electrical conductivities. It is a light gray, metallic-looking material.

The oxidation resistance of hafnium diboride 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 diboride is generally immediately available in most volumes. Ultra-high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered.

Applications of Hafnium Diboride Powder

Hafnium diboride 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 diboride 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.


Packing of Hafnium Diboride Powder

Standard Packing:

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.

ATTs’Hafnium Diboride Powder is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
