Fiber-reinforced ceramic green body and sintered ceramic article obtained therefrom

摘要

A fiber-reinforced ceramic green body having enough green strength and handling strength. The fiber-reinforced ceramic green body is obtained by molding a ceramic composition comprising a ceramic powder, a sintering aid powder, an organic fiber, an aqueous dispersion medium and an optional dispersant. The organic fiber is contained in the ceramic green body in an amount of 0.2-3 parts by weight based on 100 parts by weight of a total of the ceramic powder and the sintering aid powder and uniformly dispersed throughout it. The average length of the organic fiber is 300-1000 mu m and the average diameter is 2.5-30 mu m. The organic fiber is preferably a synthetic high polymer such as polyester, nylon, etc., and preferably has a hydrophilic nature imparted by surface treatment. <IMAGE>
