Abstract

Phases and their relations in the Y0_1.5-BaO(BaCO₃)-SrO-CuO system at 900°C in air have been studied mainly by the powder X-ray diffraction method. It was found that two new phases with compositions of (Y, Ba, Sr)₂CuO₂(CO₃)_y, Bs.s, and Y:Ba:Sr:Cu = 0.5:0.7:1.0:1.0, N, formed in this system. The newly found phase Bs.s was isostructural with the oxycarbonate Sr₂CuO₂(C0₃). The phase N has an orthorombic sturucture with lattice parameters of a=3.855Å, b=3.764Å, and c=12.69Å.
