METHOD OF PRODUCING OXIDE SINGLE CRYSTAL

摘要

PROBLEM TO BE SOLVED: To provide a new method for producing an oxide single crystal whose oxidation state is enhanced (and which is liable to be oxidized). SOLUTION: The single crystal is formed by heating a solution or a melt of a raw material of the oxide single crystal, in which at least one of silver or silver compounds has been added, and gradually cooling. It is possible to give a possibility of being oxidized to a compound generally hard to be oxidized by this method. Thereby, this method has a merit capable of being widely applied to improve the superconducting properties or to discover a new superconductor.
