Abstract
DTA-DTG, X ray diffraction and metallographic measurements at differen t temperatures and partial oxygen pressure in the isoplethic cut ''(Bi ,Pb)(2)Sr2CuOx-CaCuO2'', were carried out to analyze the influence of partial constraint oxygen pressure on phase transformations. An isobar ic invariant equilibrium has been found in the Po-2 range 0.5-1. Suppl ementary phase appearing at invariant equilibrium is (Sr,Ca)(3)Cu5Oy. That phase fixes oxygen and then the weight loss is stopped.
