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 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 (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 temperature 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 applications.
