Hafnium Diboride (HfB2) Powder: Applications
Hafnium diboride exhibits high thermal conductivity as well as high electrical conductivity. It is mainly used in aviation, aerospace, high-speed aircraft nosecones, and high-temperature materials. It is a good candidate for high-temperature materials and is commonly used as ablative material when exposed to high temperatures.

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 and 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 the early transitional metals carbides, borides, and nitrides possessed surprisingly high thermal conduction, resistance to oxidation and good mechanical strength. ZrB2 (and HfB2) of composites containing around 20% volume SiC has the best performance.
UHTC is an early transition metal boride (HfB2), carbide (HfC), nitride (ZrB2), and oxide. The focus of current efforts is heavy early transition metal diborides 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 point and higher thermal conductivity compared to carbides and Nitrides. This gives them a good thermal shock resistance, and makes them suitable for many high temperature thermal applications.
