Abstract
Powder of ceramic materials is produced by mixing a powder of a basic ceramic composition, a solvent and a surfactant to prepare a slurry, adding at least one unsaturated fatty acid salt containing an additive metal element to the resultant slurry, polymerizing the at least one unsaturated fatty acid salt with a polymerization initiator to form a polymer of at least one unsaturated fatty acid salt, drying the resultant slurry to form a layer of the resultant polymer on particle surfaces of the basic ceramic composition, and then calcining the resultant coated powder of the basic ceramic composition.
