Characteristic
Zirconium diboride (ZrB2) is a highly covalent refractory ceramic material with a hexagonal crystal structure. ZrB2 is an ultra high temperature ceramic (UHTC) with a melting point of 3246 °C. This along with its relatively low density of ~6.09 g/cm3 (measured density may be higher due to hafnium impurities) and good high temperature strength makes it a candidate for high temperature aerospace applications such as hypersonic flight or rocket propulsion systems. It is an unusual ceramic, having relatively high thermal and electrical conductivities, properties it shares with isostructural titanium diboride and hafnium diboride.
Chemical formula：ZrB2
Molar mass：112.85 g/mol
Appearance：grey-black powder
Density：6.085 g/cm3
Melting point：~3246 °C
Solubility in water：Insoluble
Crystal structure：Hexagonal, hP3
Application
It can be used as aerospace high temperature resistant material, wear-resistant smooth solid material, cutting tools, thermocouple protection tube and electrode material for electrolysis of molten compounds.Especially suitable for use as a surface for ball bearings.
