Hafnium diboride is a kind of gray crystal and has metallic luster, with high electric conductivity and stable chemical property. Besides, it is hardly reacted with all chemical reagents (except for Hf) in indoor temperature. It, a kind of new-type ceramic material with high-temperature comprehensive performance such as high melting-point, high thermal conductivity, inoxidizability, etc., is mainly applied in fields such as super high-temperature ceramics, high-speed aircraft nose cone and aerospace, etc.


Hafnium diboride is a gray-black metallic luster crystal whose crystal structure belongs to the hexagonal system. As an excellent ultra-high temperature ceramic material, hafnium diboride (HfB2) has a high melting point (3380 ℃), it is often used in the anti-ablation material in high-temperature oxidation environment and has the characteristics of high hardness, high modulus, high thermal conductivity and high conductivity. It is widely used in wear-resistant coatings, refractory materials, Cutting tools and aerospace thermal protection systems and other fields.
