Hafnium Diboride (HfB2) Powder: Applications
Hafnium diboride exhibits high hardness, modulus, thermal conductivity, as well as electrical conductivity. It is mainly used in aviation, aerospace, and high-temperature ceramics. It is used as a ablative in the high temperature oxidation environment and can be a candidate material for high-temperature materials.

What is Ultra-High-Temperature Ceramics (UHTCs)?
UHTC is a class of ceramics with exceptional stability at temperatures exceeding 2000 degC. It has been investigated for use in thermal protection systems, coatings to protect materials from high temperatures, as well as bulk material heating elements.
The AIR Force Materials Laboratory funded the development of a high-temperature material in the early 60s to meet the needs of the aerospace industry. This new material was designed to withstand hypersonic aircraft, such as the Boeing X-. They found, through a study of the fire-resistance of binary ceramics that early transitional metals such as borides, carbides, and nitrides possessed a surprising thermal conductivity, resistance to oxidation and mechanical strength. ZrB2 (and HfB2) of composites with around 20% SiC in volume have the highest performance.
UHTC is an early transition metal nitride (or carbide), boride (or boride carbide), and oxide. Current efforts are focused on heavy early-transition metal borides like hafnium diboride and zirconium boride. UHTCs that are being studied for TPS include titanium carbide, titanium nitride, thorium dioxide and other composites.
Diborides are characterized by a lower melting temperature and higher thermal conductivity compared to carbides and Nitrides. This gives them a good thermal shock resistance, and makes them an ideal material for many high-temperature applications.
