Application

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.
