ABSTRACT:
Superconducting oxide ceramics having a high density of superconducting current are formed without making use of very high temperatures higher than 1000.degree. C. Superconducting oxide material is placed in a crucible, melted and fired at a relatively low temperature. During the melting and firing step, the partial pressure of oxygen is reduced in order to lower the melting point of the ceramic. After the firing, the partial pressure of oxygen is increased.
