Abstract
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 (Tg and Tx) and density have been determined and the thermal stability is discussed following the ΔT (Tx–Tg) parameter. The electrical conductivity of glasses increases with the LiCl content and reaches a maximum of 1.2 μS/cm at room temperature. Finally, correlations between the conductivity and the structure analyzed by Raman spectroscopy were highlighted.
