Divalent Magnesium Ionic Conduction in the Magnesium Phosphate Based Composites

By intentionally varying the mixing ratio to the nonstoichiometric region, spontaneous dispersion of the Zr2O(PO4)2 secondary phase was successfully achieved and the Mg2+ ion conductivity was greatly improved by considerably increasing the relative density of the composite and the Mg2+ ion conducting composite showing the highest ion conductivity among the Mg2+ ionic conductors reported was developed.
