dc.description.abstractIN THIS WORK, WE PREPARED LA1?XSRXGA1?YMGYO3 (LSGM) BY THE FAST COMBUSTION METHOD AND ASSESSED THE ELECTRICAL PROPERTIES WITH RESPECT TO THE COMPOSITION AND SINTERING TEMPERATURE (1200, 1300, AND 1400 °C BY 6 H) AS AN ELECTROLYTE MATERIAL FOR THE REVERSIBLE SOLID OXIDE CELLS (RESOCS). FOR THE PREPARATION OF SAMPLES, TWO DIFERENT FUELS, SUCH AS TARTARIC ACID (TA) AND CITRIC ACID (CA), WITH CORRESPONDING NITRATE SALTS AS PRECURSORS, WERE ADOPTED FOR THE FAST COMBUSTION METHOD (AT 500 °C FOR 10 MIN). FROM THE X-RAY DIFRACTOGRAMS, TWO MAIN PHASES CORRESPONDING TO LSGM ORTHORHOMBIC (SPACE GROUP IMMA) AND LSGM-CUBIC (SPACE GROUP PM-3 M) WERE IDENTIFED. FROM THE LITERATURE, BOTH STRUCTURES ARE REPORTED AS HIGH OXYGEN ION CONDUCTIVE SPECIES, BUT NORMALLY THEY ARE NOT REPORTED TO APPEAR TOGETHER. ADDITIONALLY, IN SOME CASES, AN ISOLATING (SECONDARY) PHASE OF LASRGAO4 IN A LOW CONCENTRATION
