摘要：
Series of Li1.5Al0.5Ge1.5(PO4)(3) glass ceramic samples were prepared in this work through the change of heat treatment temperature from 650 to 1050 degrees C. The structures of glass ceramic samples were characterized by means of high temperature X-ray diffraction and Field Emission Scanning Electron Microscope. And the lithium ionic conductivity was analyzed through AC impedance spectroscopy. Through heat treatment at 850 degrees C for 4 h for the base glass sample, we obtained a maximum conductivity of 5.8 x 10(-4) S/cm at room temperature.
