Hard wearing zirconia ceramic substrate yttria-stabilized zirconia plate
Zirconium oxide ceramics are white, yellow or gray when containing impurities, and generally contain HfO 2, which is not easily separated. Pure ZrO2 has three crystal states under normal pressure. The production of zirconia ceramics requires the preparation of high-purity, good dispersion properties, ultra-fine particles, narrow particle size distribution, zirconia ultrafine powder preparation methods, zirconia purification mainly chlorination and thermal decomposition, alkali metal Oxidative decomposition method, lime melting method, plasma arc method, precipitation method, colloid method, hydrolysis method, spray pyrolysis etc.
