FORMED PRODUCT FOR PRODUCING OXIDE SUPERCONDUCTOR, METHOD FOR PRODUCING OXIDE SUPERCONDUCTOR, AND OXIDE SUPERCONDUCTOR

摘要

PROBLEM TO BE SOLVED: To provide a formed product for producing an oxide superconductor capable of providing the oxide superconductor by being made to orient the whole thereof, a method for producing the oxide superconductor, and the oxide superconductor obtained from the formed product. SOLUTION: This formed product 1 used when producing the oxide superconductor in a partially molten state by heating has a shape in which the center part 11 on a top face 10 thereof is projected from a peripheral part 12 on the top face 10. The method of production is characterized by comprising heating the formed product 1 to be the partially molten state and gradually cooling to crystallize. Besides, the oxide superconductor is produced by the method of production and is approximately plane at the top face.
