Based on the results of X-ray diffraction analysis of quenched samples and coulometric titration measurements, the phase equilibria of the La-Sr-Mn-O system at 1100°°C were examined and are illustrated in the form of phase diagrams. Two types of solid solutions La 1Ψx Sr x MnO 3Ψy and (La 1Ψx Sr x )
## Phase equilibria in the system SrO-CaO-CuO have been studied under high oxygen pressures. The recently discovered non-superconducting binary phase, Sk7413, Cu02, which is stable only under high oxygen pressure, forms a complete range of solid solutions with the structurally related phase, Ca,.,
