STUDY OF THE CONDUCTING BEHAVIOR OF AN AMORPHOUS Li+ CONDUCTOR IN THE ISO-THERMAL TREATMENT PROCESS
等温热处理过程中一种非晶态Li+导体电导行为的研究

The con ducting behavior of an amorphous Li+ conductor B2O3-0.7Li2O-0.7LiCl-0.1Al2O3 has been measured continuously and automatically by using the a.c. Volt-Ampere method in the isothermal treatment process at a certain temperature below its transition temperature. It was found that the conductivities of specimens increased at the initial stage and decreased monotonically after passing a maximum, and then two flat steps appeared. Comparing these results with that obtained by DSC and XRD analysis, we confirmed that the presence of the maximum of the conductivities is principally due to the amorphous phase separation, and the flat steps on the diagram of the conductivities are due to the amorphous crystallization. These results were discussed preliminarily in the view of the interface effects between different phases.
