Hafnium Diboride Powder HfB2 is an application
Hafnium diboride features high hardness and modulus as well as high thermal conductivity. It also has high electrical conductivity. High-temperature ceramics, aeronautics, aviation and many other industries are where it is most commonly used. It can be used to make high-temperature ceramics.
What is Ultra-High-Temperature Ceramics (UHTCs)?
Ceramics at ultra high temperatures (UHTC).
These materials are part of the refractory class that exhibits excellent resistance to temperatures above 2000°C. They have been investigated for their potential as materials for thermal protection (TPS), materials for bulk material heating elements, or coatings for materials that can withstand high temperatures.
In the 1960s, the aerospace industry was looking for high-temperature materials. The AIR Force Materials Laboratory began funding the research and development of a material that would withstand hypersonic aircraft like the Boeing X-. The fire resistance of binary ceramics was studied in detail. They found that the transition metals of Borides, Carides and Nitrides, as well as their oxidation and thermal resistance were very high. ZrB2 & HfB2 are the most effective composites that contain about 20% SiC.
UHTC, broadly speaking, is an oxide, carbide and nitride that occurs in early transition metals. Current research focuses on early transition metal heavy borides like zirconium triboride, (ZrB2), and hafnium disboride. The TPS application of UHTC is also being explored by hafnium (HfN), zinc nitride, (ZrN), titanium (TiC), titan nitride [TiN], thorium dioxide (“ThO2)), Tantalum carbide („TaC”) and other related composites.
They have a higher thermal conductivity and lower melting point than carbides, nitrides and nitrides. These properties make them suitable for thermal applications at high temperatures.
