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, 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 ceramic refractory which has an excellent thermal stability. It can be used for thermal protection systems, coatings to protect materials from high temperatures or 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 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 reasonable mechanical strengths. 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. Current efforts are focused on heavy early-transition metal borides like hafnium diboride and zirconium boride. UHTC for TPS is also being investigated in hafnium carbide (TiC), zirconium carbide, titanium nitride, thorium oxide (ThO2) & Tantalum carbide.
Diborides are characterized by a higher thermal conduction but lower melting point than carbides or nitrides. This gives them excellent thermal shock resistance, and makes them suitable for many high temperature thermal applications.
