Abstract

A description of the Ge – Sb – S – I glass system preparation method by interaction of germanium iodide (IV) and antimony iodide (III) with sulfur melt is given. The prepared samples were investigated by the methods of X-ray spectral microanalysis, differential scanning calorimetry, infra-red spectroscopy, Raman spectroscopy, laser mass spectrometry. The content of silicon impurity was 1–2 ppm wt., of metals – not more than 0.5 ppm wt. The glasses are characterized by high transparency in 2–10 µm spectral range..

Keywords
