PCT No. PCT/JP89/00092 Sec. 371 Date Sep. 27, 1989 Sec. 102(e) Date Sep. 27, 1989 PCT Filed Jan. 30, 1989.It relates to calcium phosphate series compound ceramics in which heat-resistant inorganic short fibers such as flawless SiC or Si3N4 are three-dimensionally dispersed in a matrix composed of calcium phosphate series compound and entangled with each other to form a high strength shaped body as well as a method of producing the same. And also, it relates to a high density silicon carbide ceramic in which biological glass is impregnated and filled in a porous shaped body, which provides composite ceramics having high strength and high toughness and suitable as a heat-resistant structural material or a material for bio hard texture.
