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-speed aircraft nosecones. It is a good candidate for high-temperature materials and is commonly used as a 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, as well as bulk materials 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 the harsh environments of hypersonic planes such as Boeing X-. They found, through a study of the fire-resistance of binary ceramics that the early transitional metals carbides, borides and nitrides possessed a surprising thermal conductivity. ZrB2 (and HfB2) of composites with around 20% SiC in volume have the highest performance.
UHTC is an early transition metal boride (HfB2), carbide (HfC2), nitride (ZrC2), and oxide. Current efforts are focused on heavy early-transition metal borides like hafnium diboride and zirconium boride. UHTC being studied for TPS applications includes hafnium carbide (TiC), zirconium carbide, titanium nitride, titanium nitride and related 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.
