摘要：
Chalcogenide samples were synthesized by melting-quenching method in the GeS2-Ga2S3-LiCl system to determine its vitreous domain. Different series were investigated by varying either the GeS2/Ga2S3 ratio or the molar content of LiCl. The study allows to establish that a maximum of 20 mol% of LiCl can be added in the glass composition. The glass transition and onset crystallization temperatures (T-g and T-x) and density have been determined and the thermal stability is discussed following the Delta T (T-x-T-g) parameter. The electrical conductivity of glasses increases with the LiCl content and reaches a maximum of 1.2 mu S/cm at room temperature. Finally, correlations between the conductivity and the structure analyzed by Raman spectroscopy were highlighted.
