Abstract

We report our investigations on Lanthanum Strontium Magnesium Gallate, La0.8Sr0.2Ga0.8Mg0.2O3 (LSGM) powder was synthesized by glycine nitrate method. Precursor and calcined particles of LSGM was characterized using Thermogravimetry (TGA), Fourier transform infrared spectra (FTIR), X-ray diffractometry (XRD), and Scanning electron microscopy (SEM). The precursors were calcined at 1000oC, 1100oC, 1200oC, and 1300oC (12hrs), LSGM contained very small amounts of impurities peaks, detected by XRD. The powders calcined at temperature 1400oC had main crystal structure of LSGM. FTIR analysis demonstrates the presence of nitrates and carbonates. The calcined powders of LSGM showed uniform microstructures with nearly spherical morphology and average particle size of 200-300 nm.
