high quality Zirconium Boride/ ZrB2/Zirconium Diboride CAS NO.12045-64-6

What is Zirconium Boride powder ZrB2

Zirconium diboride, with the chemical formula of ZrB2 , is a kind of senior engineering material broadly used in various fields. The composite ceramic made of ZrB2 is featured with excellent performance due to high melting-point (3040℃), high hardness, high stability as well as good electrical conductivity, thermal conductivity, inoxidizability and resistance to chemical corrosion.
It is an unusual ceramic, having relatively high thermal and electrical conductivities, properties it shares with isostructural refractory diborides of zirconium and hafnium
