Phase relations for the Y-Ba-Cu-O system near 1:2:3 stoichiometric compositions at high temperatures have been studied through microstructural observation. It has been found that YBa₂Cu₃O_x decomposes into a Y₂BaCuO₅(211) plus liquid (a mixture of BaCuO₂ and CuO) phase at around 1050°C and the 211 phase further decomposes into Y₂O₃ plus liquid at around 1200°C. Even at 1500°C Y₂O₃ seems to be stable. On cooling Y₂O₃ reacts with the liquid to produce the 211 phase by peritectic solidification. At around 1000°C the 211 phase reacts with the liquid to produce the YBa₂Cu₃O_x phase again by the peritectic reaction.
