Application

Hafnium boride, a gray, hexagonal crystal solid, is primarily employed as a refractory material and sputtering target to produce films known for their wear-resistant and semiconducting properties. With a high hardness of 2900 kgf/mm² and a resistivity of 8.8 μohm·cm, it's prepared by heating a combination of HfO2, carbon, and B2O3. At a purity of 99.5%, hafnium boride is crucial in creating coatings for wear resistance and is also used in nuclear reactor control rods, hypervelocity re-entry vehicle components like ICBM heat shields, and aerodynamic leading edges. Additionally, it plays a significant role in developing high-temperature composites alongside silicon carbide (SiC).
