Abstract
Solid-phase relationships have been determined for the Bi 2O 3-SrO-CuO system at 800°C in air with and without Li 2CO 3 mineralizer. Two ternary compounds were detected with Bi:Sr:Cu ratios of approximately 2:2:1 and a solid-solution phase 11-x:9+x:5 with 0≤x≤0.4. The solid-solution phase is a 9 K superconductor at x=0.4. Two additional compounds with Bi:Sr:Cu ratios of approximately 4:9:1 and 2:7:2 are apparently stabilized by the presence of Li 2CO 3, but do not form without it. X-ray crystallographic data are provided for each compound. Ramifications for quaternary Bi:Sr:Ca:Cu-0 superconductors are discussed.
