ABSTRACT:
A high Tc superconducting ceramics material is produced by mixing ceramic constituents with an alcohol or a freon before firing. The alcohol or freon functions to reduce the ceramics during firing so that excess oxygen can be eliminated from the superconducting structure. The superconducing ceramics then are coated with an organic resin film in order to avoid the influence of air.
