METHOD FOR MANUFACTURING MATERIAL FOR OXIDE SUPERCONDUCTOR, METHOD FOR MANUFACTURING OXIDE SUPERCONDUCTING WIRE ROD, AND SUPERCONDUCTING DEVICE

摘要

A method for manufacturing a material for an oxide superconductor is provided with a step of ionizing a material, which includes atoms that compose the oxide superconductor, in a solution; a step of removing a solvent by jetting the solution in an atmosphere and manufacturing a material powder including the atoms which compose the oxide superconductor; and a step of cooling the material powder in the atmosphere to which cooling air is introduced. The concentration of carbon dioxide in the atmosphere is lower than that in the atmosphere including the ingredients of the removed solvent, the concentration of nitrogen oxide in the atmosphere is lower than that in the atmosphere including the ingredients of the removed solvent, and the concentration of water vapor in the atmosphere is lower than that in the atmosphere including the ingredients of the removed solvent. Thus, density and purity of the oxide superconductor can be improved.
