Hafnium Diboride Powder Description

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.

Stanford Advanced Materials (SAM) produces many standard grades when applicable, including Mil Spec (military grade), ACS, Reagent and Technical Grade, Food, Agricultural and Pharmaceutical Grade, Optical Grade, USP, and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards.
