ABSTRACT:
The present invention relates to a process for preparing an oxide superconductor having a high critical current density, a uniform structure and an excellent mechanical property and thermal stability, which comprises heating raw material powders of a REBaCuO system at 1050.degree. C. or higher, cooling the material for solidification, pulverizing and mixing the solidified material to homogeneously disperse the structure of the solidified material, molding the material, optionally mixed with silver oxide or silver, into a predetermined shape, and reheating the molding to 1050.degree. C. or higher to grow a superconducting phase.
