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 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 degrees C. 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 binary ceramics' fire resistance, that the early transitional metals carbides, borides, and nitrides exhibited surprisingly high thermal conduction, resistance to oxidation and good 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. Hafnium diboride and zirconium boride are two heavy early transition metals borides that are currently being investigated. UHTC being studied for TPS applications includes hafnium carbide (TiC), zirconium carbide, titanium carbide, titanium nitride and related composites.
Diborides are characterized by a higher thermal conduction but a lower melting temperature than carbides or nitrides. This gives them optimum thermal shock resistance, and they can be used in many high-temperature applications.
