Abstract: A series of Fe-doped Na3Mn2-xFex(P2O7)(PO4) (x = 0, 0.2, 0.4) (abbreviated as NMFP-0/NMFP-0.2/NMFP-0.4) compounds have been successfully prepared using the sol-gel method. The Rietveld refinement results indicate that single-phase Na3Mn2-xFex(P2O7)(PO4) with an orthorhombic structure can… read more here.
