Abstract
A high Tc superconducting ceramic material is produced by a method in which a mixture of chemicals in suitable amounts is compacted into a desired form. The compacted mixture is then fired and, at the same time, an electric current is caused to pass through the compacted mixture in a predetermined direction. By virtue of the passage of the current through the material during firing, the orderliness of the molecular arrangement is enhanced and an elevated transition temperature Tc is obtained.
