摘要： A method of producing ceramic articles having a density substantially equal to the theoretical density comprises heating a highly porous preliminary molding made of a ceramic powder to obtain a preliminarily sintered molding of a porosity below 30%, followed by sintering the preliminarily sintered molding under a uniform pressure by the use of a powder acting as a pressure transmitting medium. This method permits producing a ceramic article having a desired shape, and no deformation in it.
