ABSTRACT OF THE DISCLOSURE: In the manufacture of an object of a powdered material by iso- static pressing of a body (10) preformed from the powdered mat- erial with a gaseous pressure medium, the preformed body is pro- vided with a casing (13) of glass which is made gas-impenetrable by heating before carrying out the isostatic pressing, Inside the glass casing there is arranged on the preformed body an inter- mediate layer (12) which counteracts the penetration of molten glass from the casing into the preformed body. The intermediate layer comprises a layer of one or more intermediate phases in the system Al2O3 - SiO2, for example mullite 3 Al2O3 ? 2 SiO2, or a layer containing one or more such intermediate phases as main constituent. In a preferred embodiment a layer of boron nitride is arranged inside the intermediate layer. In a pre- ferred embodiment, the powdered object consists of aluminium oxide or an aluminium oxide-based ceramic.
