- Abstract
New NASICON type materials of composition, Li3-2xAl2-xSbx(PO4)3 (x = 0.6 to 1.4), have been prepared and characterized by powder XRD and IR. D.C. conductivities were measured in the temperature range 300-573 K by a two-probe method. Impedance studies were carried out in the frequency region 10²-106 Hz as a function of temperature (300-573 K). An Arrhenius behaviour is observed for all compositions by d.c. conductivity and the Cole-Cole plots obtained from impedance data do not show any spikes on the lower frequency side indicating negligible electrode effects. A maximum conductivity of 4.5 × 10-6 S cm-1 at 573 K was obtained for x = 0.8 of the Li3-2xAl2-xSbx(PO4)3 system.
