Abstract

PURPOSE:To impart excellent superconductivity to the title material by cooling the calcined powder or sintered body powder to a temp. lower than the critical temp. of the superconductive material, injecting the powder into a magnetic field to classify the powder by the flying distance, and using the classified powder. CONSTITUTION:An oxide-based material such as A-B-Cu-O is used as the superconductive material, and the powders of the respective materials are uniformly mixed in a specified ratio. The mixed powder is heat-treated to obtain the calcined powder or sintered body powder. The obtained powder is introduced into an injection pipeline 4, into which the gaseous nitrogen or gaseous helium cooled to a temp. lower than the critical temp. of the superconductive material is introduced, and sent under pressure. The powder 8 is injection into a cooling vessel 2 from an injection port 3 along with the injection gas. The powder 8 is passed through a static magnetic field generated by the magnet 7 with the N pole at the upper part of the cooling vessel 2 and the S pole at the lower part, classified by the difference between the flying distances due to the Meissner effect, and separately collected in receivers 6 and 7.
