Abstract: | The homogeneity area boundaries of La 1-xBa xMn 1-yCryO 3 solid solutions possessing orthorhombic and rhombohedral structures were established. A state diagram at 1373 K in air in the quaternary oxide system LaMnO 3-BaMnO 3-BaCrO 4-LaCrO 3 was drawn for the first time. Partial substitution of Mn with Cr in La 1-xBa xMnO 3 stored the thermal compatibility of the cathode with the any traditionally used electrolyte but reduced the electric conductivity of the potential cathode. Based on the linear lengthening measurements of La 1-xBa xMn 1-yCryO 3 and Sr 2NiMoO 6 samples the values of the thermal expansion coefficients were calculated. It was established that the temperature of the structure transition from a tetragonal to a cubic phase in Sr 2NiMoO 6 occurred at 508 K. It was stated that double perovskite Sr 2NiMoO 6 in air did not react with (La 0.9Sr 0.1) 0.98Ga 0.8Mg 0.2O 3 up to 1073 K. © 2012 al-Farabi Kazakh National University. |
