摘要：
Single phase La0.9Sr0.1Ga0.8Mg0.2O3-delta (LSGM9182) was synthesized by a polymeric precursor route. The XRD pattern after calcination at 1300 degrees C for 6h indicates the formation of the perovskite without the presence of secondary phases. XRD, FTIR and TG-DTG measurements were used to examine the powder precursor as well as the intermediate and final products. SEM images indicated the small grain size of the final product. The conductivity of the sintered sample was examined by means of a.c. impedance spectroscopy and was found to be 9.10(-2) S/cm at 800 degrees C similar to the typical value of LSGM materials.
