Abstract

Glass formation has been studied in the ZrF4-BaF2-MnF2 ternary system. Two different vitreous areas have been observed. One of them corresponds to high concentrations in manganese fluoride, which confirms the vitrifying ability of MnF2. The stability of these glasses versus devitrification has been increased by the incorporation of AlF3 and ZnF2. Glass compositions and partial vitreous areas are reported in the ZrF4-BaF2-MnF2-AlF3-ZnF2 system. The evolution of characteristic temperatures and density versus chemical composition has been studied. These glasses have a potential for phoinduced phenomena.
