Ceramic sintered bodies and a process for manufacturing the same.

摘要

High density fine ceramic sintered bodies are disclosed, which have the maximum pore diameter of not more than 10 mu m and porosity of not more than 0.5%. A process for producing such high density fine ceramic sintered bodies comprises the steps of mixing a ceramic raw material powder with a sintering aid, grinding the resulting, granulating and shaping the mixture, and firing the shaped body. The granulated powder is once forcedly dried, and as necessary is subjected to addition of water and/or sieved to obtain a uniform granulated powder having a given amount of water.
