摘要
The actual technology require raw material of high purity to obtain functional ceramics with a high performance and reliability. Several synthesis methods have been developed to control the chemical purity, particle size, distribution and morphology of ceramic powders. The solid phase precipitation in the solution bulk permit the control of the physical characteristics of a ceramic powder through of the nucleation and growth processes in the solution. This synthesis method have good possibilities in the industry although it have several problems to resolve. This paper indicate the basic physical chemistry principles that occur in the precipitation process and the characteristics of the control precipitation method.
