Na3MgTi(PO4)3 phosphate exists in both crystalline and vitreous forms. The glass-crystal transformation was investigated using DTA, XRD, Raman spectroscopy and ionic conductivity. The crystalline phase which belongs to the Nasicon type family structure, space group R3, contains isolated TiO6 octahedra whereas the corresponding glass contains Ti-O-P and Ti-O-Ti linkages. The Mg2+ ions are located in the framework for the crystalline phase while in the glass they are in the modifying network.
