✦ Synopsis
The subsolidus phase relations for the ternary system, BiO 1.5 -YbO 1.5 -CuO, are investigated by the powder X-ray diffraction method. The system can be divided into six three-phase regions and three two-phase regions. There exist two solid solutions Bi 1؊x Yb x O 1.5 (0.054 4x4 40.35) and Yb 1؊x Bi x O 1.5 (x4 40.02). The former solution exhibits a tetragonal structure with 0.054 4x( (0.15 which is isostructural to -BiO 1.5 , while a cubic structure with 0.154 4x4 40.35 is isostructural to -BiO 1.5 . A new compound with the composition close to Yb 12 Bi 12 CuO y is found.
