How do you define it? Zirconium Diboride Chrome ? Zirconium Diboride (ZrB2), a type of covalent high refractory clay material has a hexagonal structure. It has an ultra-high temperature (UHTC), melting point of 3246.6°C. Because of its low density (6.09 g/cm3), and excellent high-temperature resistance it is a good candidate for high-temperature aerospace uses such as rocket propulsion systems or hypersonic flight. The unusual ceramic is extremely thermally and electrically c
