Zirconium Diboride

Zirconium diboride is gray crystal powder, which is minor metal boride. It is heat resistance, which show very high strength both at room temperature and high temperature. ZrB2 gets good thermal shock resistance and small electrical resistance. There are four production methods of ZrB2, direct method, boron carbide method, carbon reduction method and vapour deposition method. Zirconium oxide or zirconium metal is the raw material.

Zirconium boride uses as composite material normally. It is raw material for cutting tools and electronic elements, especially fitting for surface of antifriction bearing ball.

ZrB2 is raw material for protective tube of different temperature thermocouple, electrode material of electrolytic melting compounds.
