Superconducting bulk ceramics in the form of rods, tubes, rings or blocks are best produced from the 2212 phase of the title system. Until now, however, the 2212 single‐phase region, which also involves regions of varying Sr/Ca ratio and varying Bi contents, has not been unambiguously characterized. In this work, the 2212 single‐phase region is defined and the critical temperature ( T c ) correlated with the chemical composition.
