Abstract:

In this research, a nanostructured NASICON-type (Na-Super Ionic Conductor) based on Lithium, i.e. LiAlo-Ti,(PO4)3 (LATP), was synthesized through modified Pechini-type sol-gel method. Watersoluble amonium citrate peroxotitanate metal complex was used as precursor instead of conventional alkoxide, leading to the production of monophase nanostructure. X-Ray diffractometry CXRD) and scanning electron microscopy (SEM) were performed for phase analysis and the 2 Sima Arefi, Pirooz Marashi et al.morphology investigation of the produced powders, respectively. Moreover, differential thermal analysis (DTA) was employed to determine the calcination and crystallization temperatures to optimize the synthesis temperature. The modified Pechini-type method allowed obtaining well crystallized LATP at a much lower temperature and with a shorter synthesis time in comparison with the conventional solid-state reaction.
