ABSTRACT:
A process for producing a superconducting ceramic material using microwave energy and the superconducting ceramic material produced thereby. A preferred process comprises the steps of mixing powders of Y.sub.2 O.sub.3, CuO and at least one member selected from the group consisting of BaCO.sub.3 and BaO, and then subjecting the resultant powder mixture to heat treatment in microwave energy. In a preferred embodiment, the heat treatment step comprises the steps of calcining, sintering and annealing, at least one of the calcining and annealing steps using microwave energy.
