Abstract Phase transitions of the compositions Y1±xBa2±yCu3±zO72212;δ (x,y=0–0.2;z=0–0.5; step 0.1) were studied by DSC in argon atmosphere in the temperature range 1050–1300 K. The formation of three polymorphous modifications of the 123 phase was observed. The solubilities of yttrium, barium and copper oxides in every modification were determined. TheT-x-y phase microdiagram for the 123 phase was mapped out.
