An object of a metallic material or other ceramic material than silicon nitride or than a material having silicon nitride as its main component is manufactured by isostatic pressing of a body preformed from a powder of the metallic or ceramic material, whereby the preformed body is embedded in glass, for example embedded in a mass of glass particles, and the embedment, with the body and the embedment placed in a vessel which is dimensionally stable at the temperature at which the sintering of the metallic or ceramic material is carried out, is transferred to a melt having a surface limited by the walls of the vessel, below which surface the preformed body is located, and a pressure necessary for the isostatic pressing of the preformed body then being applied on the melt by a gaseous pressure medium. |
