Abstract

X-ray diffraction spectra are studied in the two series of La0.9Sr0.1Ga0.8Mg0.2O3 δ (denoted as LSGM). The comparison of the enlarged portion of XRD spectra between the experimental samples and samples in the card bas has been made to detemine their crystal structures at room temperature. The comparison results reveal that the two series of samples of La0.9Sr0.1Ga0.8Mg0.2O3 δ crystallized in different structures by different synthetic routes. It suggests that the sample prepared by solid state reactions can be identified as monoclinic (I2/a, No.15) phase, whereas the other sample by laser rapid solidification belongs to orthorhombic (Imma, No. 74) phases. The results of determination of crystal structure from the comparison of experimental XRD spectra to that in card base were in consistent with the analysis of Vasylechko's structure models.
