Properties of oxychloride glass system in relation to fast ion conduction

A series of glasses based on the 0.2MoO₃-0.3P₂O₅-(0.5-x)PbO-xPbCl₂ system was prepared and their physical and thermal properties were investigated. This system provides a wide and stable glass formation range in which improvement of ionic conductivity would be achieved. The composition dependence of some properties was discussed in terms of the possible role of chlorine ions in the glass structure. The experimental data suggested that Cl^- ion accommodation could form additional preferential pathways which are important for the conduction mechanism. The glass corresponding to composition x = 0.45 was found to have the highest conductivity value (~10^-2 S cm^-1) which recommends it for possible technological applications.
