Preparation of zirconia ceramic powder

The production of zirconia ceramics requires the preparation of powders with high purity, good dispersion properties, ultra-fine particles and narrow particle size distribution. There are many preparation methods for zirconia ultra-fine powder. The purification of zirconia mainly includes chlorination and thermal decomposition, alkali metal Oxidative decomposition method, lime melting method, plasma arc method, precipitation method, colloid method, hydrolysis method, spray pyrolysis method, etc. Powder processing methods include co-precipitation method, sol-gel method, evaporation method, supercritical synthesis method, microemulsion method, hydrothermal synthesis method, network and vapor deposition method, etc.
