ABSTRACT:
A sintered ceramic body is manufactured first by preparing a composition containing a binder and a ceramic powder having a particle size distribution given such that 0 to 1 weight % of ceramic particles with a particle size of less than 0.2 .mu.m, 0 to 2 weight % of ceramic particles with a particle size of 0.2 .mu.m to less than 0.5 .mu.m, 5 to 15 weight % of ceramic particles with a particle size of 0.5 .mu.m to less than 1.0 .mu.m, 5 to 15 weight % of ceramic particles with a particle size of 1.0 .mu.m to less than 1.5 .mu.m, 5 to 15 weight % of ceramic particles with a particle size of 1.5 .mu.m to less than 2.0 .mu.m, and 50 to 80 weight % of ceramic particles with a particle size of not less than 2.0 .mu.m. The prepared composition is then injection-molded into a predetermined shape. The binder is removed from the molded body, and the binder-free molded body is sintered.
