Abstract

New fluoroindate glasses have been synthesized by the incorporation of NaF, CdF₂ and PbF₂ in vitreous compositions based on the InF₃–YF₃–BaF₂–SrF₂ system. Systematic investigations were implemented in the different systems with a constant amount of 45% InF₃ and 5% YF₃. The corresponding vitreous areas are reported. Relative resistance to devitrification was evaluated using stability factors. The incorporation of NaF, CdF₂ and PbF₂ had only limited influence on the glass stability. Optimized glass compositions are reported. Important physical properties, including characteristic temperatures, densities and refractive indices have been measured and correlated with composition.
