Abstract
Calcium phosphate series compound ceramics are provided in which heat-resistant inorganic short fibers such as flawless SiC or Si.sub.3 N.sub.4 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. Also, a high density silicon carbide ceramic is provided in which biological glass is impregnated and filled in a porous shaped body. These composite ceramics have high strength and high toughness and are suitable as a heat-resistant structural material or a material for bio hard texture.
