摘要

A process for producing superconducting (Bi. T1 )-Ca-(Sr, Ba)-Cu-O ceramic suffering less variation in components, which comprises mixing a calcium compound, a strontium or barium compound and a copper oxide, each of which has a low vapor pressure among the powdery starting materials, in predetermined proportions, subjecting the mixture to primary firing at a predetermined temperature of 850 to |050°C to form a Ca-(Sr, Ba)-Cu-O oxide, mixing this oxide with a bismuth or thallium oxide, each of which has a high vapor pressure among the starting materials, and subjecting the mixture to secondary firing at a predetermined temperature of 500 to 820°C.
