Zr2Li(PO4)3, Zr2Li(PO4)3-0.3Li2O, Zr2Li(PO4)3-0.3Li3PO4, Zr1.7Li1.3La0.3(PO4)3: Ionic Conduction

A study was made of conductivity and phase transitions in Li-substituted materials. The results (table 24) demonstrated that a conductivity enhancement in various systems was associated with the formation of solid solutions that were based upon the substitution: M4+ 4Li+.
