Fluoride glasses in the InF3–GaF3–YF3–PbF2–CaF2–ZnF2 system Original Research Article

New glasses have been synthesized in a multicomponent system based on indium fluoride. Samples of a few mm in thickness were obtained. They are transparent and homogeneous. Main physical properties such as density, characteristic temperatures, density, thermal expansion and refractive index have been measured. The evolution versus composition is reported for samples with the formula: (35−x) InF3–xGaF3–10YF3–25PbF2–15CaF2–15ZnF2. Tg lies between 260 and 296 °C while melting starts around 480 °C. Glass samples are stable at room temperature. By comparison with other standard fluoride glasses, they exhibit higher refractive index and density.
