Abstract

The structure and physicochemical properties of glasses in the (AsSI)1−x (As2S3) x and (AsSeI)1−x (As2Se3) x systems are investigated. It is demonstrated using 127I Mössbauer spectroscopy that the structure of the glasses under study is built up of the structural units AsS3/2 (AsSe3/2), which correspond to the compounds As2S3 (As2Se3), and the ternary structural units, which correspond to the compounds AsSI (AsSeI). In turn, these structural units are connected into a three-dimensional network. The proposed model accounts for the observed linear dependences of the physicochemical properties (density, microhardness, glass transition temperature) of the glasses on the composition.
