| Abstract: | In the present study, the electrical properties of lithium-based Li1.3Al0.3???x Y x Ti1.7(PO4)3 (LAYTP) system is reported. Yttrium is a rare earth element and has been found to be an excellent sintering aid in ceramic electrode materials. Earlier attempts to replace the tetravalent Ti4+ using trivalent cations like Al3+, Y3+, In3+, and Sc3+ in rhombohedral NASICON structure have resulted in enhanced electrical conductivity. The effect of trivalent cation Y3+ doping in an optimized system Li1.3Al0.3Ti1.7(PO4)3 (LATP) is discussed. The electrical properties of this ceramic compound in temperature range of 303 to 423 K and in the microwave frequency range of 20 MHz to 1 Hz were studied for the LAYTP system using impedance spectroscopy. The role of yttrium to improve the density of the material and thereby the study of the grain and grain boundary is explored. |
