Abstract

PURPOSE: To improve superconducting characteristics, by melting and solidifying a granule material blended to ceramics based superconductor composition with a high energy density source in order to make it amorphous and then subjecting the resultant amorphous material to heat treatment for forming crystal.
CONSTITUTION: A material according to the component of superconducting material produced is selected as a granule material and previously calcined. A high density energy heat source such as electron beam, laser beam or plasma heat source is prepared and high density energy is irradiated to the granule material packed into a tubular body. The granule material is heated to a prescribed temperature and rapidly cooled at a prescribed cooling rate. At this time, at least one part of the material is made amorphous. Then the material is subjected to heat treatment for forming crystal. According to the above- mentioned method, uniformity of raw material is improved and superconductivity is stably provided to the raw material which becomes continuous body melted and solidified. Consequently superconducting characteristics are improved.
