ABSTRACT:
The invention relates to a process for producing superconductive ceramics wherein, first, a liquid alloy melt is made of metals; this is carried out at a temperature at which the melt is chemically homogeneous. The melt is subsequently atomized with an inert gas or with oxygen. In the first case, a powder develops which is oxidized in a further step whereas in the second case the oxide powder is a direct result. By means of sintering, for example, the oxide powder can be pressed to superconductive bodies of any desired form.
