| 2017-04 | LiSn1.6Ti0.4(PO4) ceramic powder was synthesized via solid state reaction and investigated for electrical and dielectric properties for use as solid electrolyte. X-ray diffraction shows that it has rhombohedral R3 ̅c NASICON-type structure with unreacted phase of SnO2. Impedance study in the temperature range 300 to 740 K and frequency range 300 kHz-3 GHz were carried out together with dielectric permittivity studies under the same conditions. The determined bulk and grain boundary conductivities are 1.39 x 10-3 S/cm and 3.39 x 10-4 S/cm at 740 K, respectively, while their corresponding room temperature conductivities are 6.31 x 10-6 S/cm and 1.72 x 10-6 S/cm, respectively. Activation energies determined from Arrhenius plot are 0.67 eV and 0.78 eV for bulk and grain boundary, respectively. The determined dielectric constant ε^' has a value of 40 at 303 K and reached a maximum of 1790 at 740 K, which is high compared to most reported values for NASICON and indicate that LiSn1.6Ti0.4(PO4) could be a promising candidate for application as solid electrolyte at elevated temperatures | .Ahmadu, .
