Abstract

Un objet de matière céramique ou métallique est fabriqué par pressage isostatique d'un corps préformé à partir d'une poudre de la matière céramique ou métallique. Le corps préformé 10 est enfoui dans du verre, par exemple dans une masse de particules de verre 16, à l'intérieur d'un récipient qui est résistant à la température à laquelle est effectué le frittage de la matière céramique ou métallique, et le verre est transformé en une fusion présentant une surface délimitée par les parois du récipient au-dessous de laquelle se trouve le corps préformé, une pression nécessaire pour le pressage isostatique du corps préformé étant appliquée au moyen d'un agent de pression gazeux sur la fusion.An object of ceramic or metallic material is made by isostatic pressing of a preformed body from a powder of the ceramic or metallic material. The preformed body 10 is buried in glass, for example in a mass of glass particles 16, inside a container which is resistant to the temperature at which the sintering of the ceramic or metallic material is carried out, and the glass is transformed into a melt having an area bounded by the walls of the container below which the preformed body is located, a pressure necessary for the isostatic pressing of the preformed body being applied by means of a gaseous pressure agent on the melt .
