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 )
The electrical conductivity and thermoelectric power of the system Mg}Fe}O were measured as functions of oxygen activity (a O2 ) and cationic composition in the temperature range 11004T/3 3C41300. The isotherms of both electrical properties underwent a conspicuous change in trend at the same, charac
