The quaternary phase relations near YBa2Cu306+ x were investigated using a solid-state ionic technique. Three invariant reactions were discovered. At 850Β°C, YBa2Cu306+ x with excess Cu, O reacts to form Y2BaC'uO5 and BaCu202 at lxl0 "3 arm oxygen , while pure YBa2Cu306+ x decomposes to Y2"~CuO5, BaC
