Abstract
Phase transitions of the compositions Y1+/-xBa2+/-yCu3+/-zO7-delta, (x ,y=0-0.2; z=0-0.5; step 0.1) were studied by DSC in argon atmosphere i n the temperature range 1050-1300 K. The formation of three polymorpho us modifications of the 123 phase was observed. The solubilities of yt trium, barium and copper oxides in every modification were determined. The T-x-y phase microdiagram for the 123 phase was mapped out.
