Overview of Zirconium Diboride Pulver Zirconium diboride (ZrB2) This is a type of high covalent ceramic material with hexagonal crystal structures. It is an ultrahigh-temperature ceramic (UHTC) that has a melting temperature of 3246degC. Its low density (about 6.09 g/cm3) and high high-temperature strength make this a good candidate for high temperature aerospace applications like…
