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 often used in high-temperature oxidation environments as a ablative material.

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, nitrides, and borides had high thermal conductivity. 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 (ZrC) and oxide. Current efforts are focused on heavy early-transition metal borides like hafnium biboride (HfB2), zirconium biboride(ZrB2), and zirconium boronitride (ZrB2). UHTCs that are being studied for TPS include titanium carbide, titanium nitride, thorium dioxide and other 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.
