ABSTRACT:
A method of making an object of superconductive material in the form of an oxide by isostatic pressing of a body preformed from a powder material with an oxygen-containing pressure medium at a temperature required for sintering of the preformed body, the powder material is an oxide of the metals contained in the superconductive material. Before the isostatic pressing is carried out, the preformed body is surrounded by a gas-tight casing with the ability to transport oxygen.
