“…The reason of the low values of conductivity and activation energy of α ' -Na 2 FePO 4 F can be a noticeable monoclinic distortion of the anionic crystal framework and the preservation of the antiferromagnetic ordering of the cation sublattice after the α → α ' phase transition. The same character of the σ ( T ) dependence was found in the dipole-ordered phases of α − Na 3 Cr 2 (PO 4 ) 3 with rhombohedral framework crystal structures [18,19]. It can be assumed that the ferrimagnetic ordering established in α -Na 2 FePO 4 F [17] is associated with the monoclinic distortion of the crystal structure of this material.…”

In this research, the structure parameters, conducting and dielectric properties of Na3Fe2(PO4)3 and Na2FePO4F polycrystals were studied obtained by solid-phase synthesis. The phase transition temperatures, conducting and dielectric parameters of Na3Fe2(PO4)3 and Na2FePO4F polycrystals were refined. A comparative evaluation of the conductive properties of Na3Fe2(PO4)3 and Na2FePO4F polycrystals is given in this article. The prospects of using of Na3Fe2(PO4)3 and Na2FePO4F are justified as electrode materials in sodium ion batteries.
