Abstract

Three Li_1+xAl_xGe_yTi _2-x-y(PO₄)₃ (0.2 ≤x ≤ 0.8; y = 0.2, 0.4 and 0.6) solid solutions were prepared as polycrystalline powders. These compounds crystallize in the NASICON-type structure, R3̄c space group, and the crystal structures were characterized by the Rietveld method with laboratory X-ray powder diffraction data. The cell parameter evolution along the three series agrees with the substitution of larger Ti⁴⁺ by smaller Ge ⁴⁺ and Al⁺³ cations. The electrical properties were characterized by an impedance study. Bulk conductivity values at room temperature are close to 10^-3 S·cm^-1 with low activation energies (≈0.25 eV).
