Abstract

For manufacturing an article of a ceramic or metallic material by sintering and simultaneous isostatic pressing of a powder of the material, the powder is enclosed in an embedding material of glass which is made impermeable to gas before the isostatic pressing is carried out with a gaseous pressure medium. The powder is introduced into the mould cavity of a mould 10 made of glass powder, the mould cavity having a shape corresponding to that of the article to be manufactured, whereafter the mould is covered with glass 14 which, together with the mould, forms an embedding material for the powder. The powder and the embedding material are then located in a vessel 15, and the embedding material is transformed into a melt having a surface limited by the walls of the vessel, below which surface the powder in the mould cavity is located, before the pressure necessary for the isostatic pressing is applied to the melt with the gaseous pressure medium. Alternatively the tube through which the mould cavity is filled may be covered with a plate of glass rather than using the covering of glass 14. <IMAGE>
