Abstract

The object of examination were oxygen-free glasses in the system Sb₂Se₃-KCl-NaF and Sb₂Se₃-BaCl₂- PbCl₂. On account of great difficulties connected with passing into the glassy state a special method of synthesizing these glasses has been developed. The glass area in the halide-chalcogenide systems was determined. The characteristic temperatures of glasses and their thermal stability were also determined. Certain properties of the glasses were investigated giving special consideration to producing stable glasses, a few millimeters thick, by using a special method of synthesis. The transmission range of the obtained glasses falls within the limit 0.65 up to 50 micrometers , at the level of 38 to 60%, and the refractive index is: n > 2.5. Material of such properties offers the possibility to obtain optical fibers of very high numerical aperture as well as special application on account of a wide transmission range.
