Abstract
A method for producing a superconducting thick film involves the steps of forming a thick layer comprising a superconducting material on a substrate; firing the thick layer formed on the substrate; subjecting the fired thick layer to cold isostatic pressing; and refiring the thick layer subjected to cold isostatic pressing.
Claims14
A method for producing an oxide superconducting thick film, comprising the steps of:
- (a) providing a substrate having a thick layer comprising an oxide superconducting material on at least one surface thereof;
- (b) firing the thick layer;
- (c) subjecting the fired thick layer to cold isostatic pressing at a pressure of at least about 1000 kg/cm.sup.2 ;
- (d) refiring the thick layer subjected to cold isostatic pressing;
- and
- (E) repeating steps (c) and (d) at least once,
- wherein the cold isostatic pressing is performed using a jig plate and a sheet having a release agent on a surface thereof interposed between the thick layer and the jig plate, wherein the release agent surface faces the thick layer.
