Electrical and Dielectric Characterization of Na0.5Li0.5Zr2(PO4)3
Abstract: Na0.5Li0.5Zr2(PO4)3has been synthesized by solid state reaction and characterized by thermogravimetry/ differential thermal analyses (TGA/DTA) in the temperature range 300 - 1573 K. X-ray diffraction measure- ments have been carried out to determine the phase of the composition and scanning electron microscopy (SEM) for microstructure evaluation. Impedance spectroscopy at different temperatures (310 - 600 K) and frequencies (300 kHz - 1 GHz) have been carried out and the dielectric relaxation behaviour was determined under the same conditions. A dc conductivity maximum value of 0.25 S/m at 580 K was observed. However, the mixed alkali effect was not observed. The material exhibited relaxation behaviour with a peak in the dielectric permitivity at 469 K. There were no structural transformations observed.
