Abstract

The processes of structural relaxation of vitreous materials with different thermal history were examined using the methods of dilatometry and Raman scattering. In the glass transition interval the coefficient of linear thermal expansion of the stabilized glass samples increases rapidly, while for tempered glasses it decreases and even takes negative values. According to dilatometric measurements, the characteristic temperatures of the glass transition intervals were determined, a qualitative estimation of structural changes was made depending on the temperature and time modes of synthesis and annealing of chalcogenide glasses..

Keywords
