(What is Hafnium Diboride HfB2 Powder)

Hafnium Diboride (HfB2) Powder

Hafnium diboride

It is also known as HfB2. Its crystal system is hexagonal.

Hafnium Diboride Powder HfB2 Physicochemical Properties

HfB2 is a ceramic with a high melting temperature (3380). High purity, small particle sizes, uniform distributions, large surface area, high activity on the surface, low density and high conductivity are some of its chemical properties. At room temperatures, hafnium Diboride reacts almost entirely with all chemical reagents other than HF.

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 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 degC. 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, borides and nitrides possessed a surprising thermal conductivity. 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 oxide), and carbide. Current efforts are focused on heavy early-transition metal borides like hafnium biboride (HfB2), zirconium biboride(ZrB2), and hafnium diboride. UHTCs that are being studied for TPS include titanium carbide, titanium nitride, thorium dioxide and other composites.

Diborides are characterized by a lower melting point 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 thermal applications.
