Method of Producing Superconducting Materials in Bulk Form.
Abstract
Bulk form of superconducting materials are produced by pouring a melt a O2-containing superconducting material into a heated mold, cooling the mold until solidification begins, removing the cast object from the mold, gradually cooling the cast object to prevent the development of thermal stresses, and then annealing the cast, cooled object to restore O2 to near equilibrium levels. The bulk form produced according to the present invention may be used as a sputtering target in the production of wires, or as a bulk form semiconductor. Patent application. (jhd)
