Abstract
The invention relates to a process for producing cylindrical or round parts of high-T.sub.c superconductor material comprising bismuth, strontium, calcium, copper and oxygen. In this process, a pre-prepared finely-divided oxide mixture with organic additives is first introduced at room temperature into a casting mold. The shaped mixture is then converted into the superconducting shaped part by subsequent thermal treatment.
Claims19
A process for preparing cylindrical or round bodies made of high-T.sub.c superconducting material comprising at least bismuth, strontium, calcium and copper, said process comprising:
- (a) preparing a mixture of the oxides of said bismuth, strontium, calcium and copper and organic additives;
- (b) shaping said mixture by introducing the mixture at room temperature into a rotating casting mold;
- and
- (c) converting the shaped mixture of step (b) by heat treating into the superconducting bodies.
