BeschreibungZirconium diboride (ZrB2) is a highly covalent refractory ceramic material with a hexagonal crystal structure. ZrB2 is known as a UHTC with a melting point of 3246C. This together with its relatively low density of B6.09 g/cm3 (measured density may be higher due to hafnium impurities) and good high-temperature strength makes it a contender for high-temperature aerospace applications, for example, hypersonic flight or rocket propulsion systems. It is an unusual ceramic with relatively high thermal and electrical conductivities.
VerwendenZirconium boride is use to improve resistance in zirconia-based, carbon-bonded refractories in contact with ferrous melts. Used in nuclear applications, aerospace refractory, in cutting tools and to protect thermocouple tubes. It also used in use of its relatively high conductivity, especially for a ceramic.
