The production of zirconia ceramics in ceramics requires the preparation of powders with high purity, good dispersibility, ultrafine particles and narrow particle size distribution. There are many methods for the preparation of ultrafine zirconia powders. The purification of zirconia includes chlorination and thermal decomposition, alkali metal oxidation decomposition, lime melting, plasma arc, precipitation, colloidal method, and so on. Hydrolysis, spray pyrolysis and so on.
Zirconia ceramics in ceramics are hard, brittle and difficult to machine. Diamond abrasives are commonly used as grinding tools. Diamond grinding wheels with different binders can be generally divided into resin bonded diamond sand, ceramic bonded diamond wheel and metal bonded diamond wheel.
