The powder of Lanthanum Strontium Magnesium Gallate, La0.8Sr0.2Ga0.8Mg0.2O3 (LSGM), was produced using the glycine nitrate method, and we present our findings. Thermogravimetry (TGA), Fourier transform infrared spectra (FTIR), X-ray diffractometry (XRD), and scanning electron microscopy were used to characterise the precursor and calcined particles of LSGM (SEM). The precursors were calcined for 12 hours at 1000oC, 1100oC, 1200oC, and 1300oC. LSGM included extremely minor amounts of impurity peaks, which were discovered using XRD. The predominant crystal structure of LSGM was found in powders calcined at 1400oC. The presence of nitrates and carbonates is confirmed by FTIR analysis. The calcined LSGM powders had homogeneous microstructures with a roughly spherical shape and an average particle size of 200-300 nm.
