(As₂S₃)₁₀₀₋x(SbSI)x (x = 80 and 90) glasses were prepared by cooling
homogenized melts from 720…750 K in cold water. Their structure and structural
changes under heat treatment of glasses are confirmed by studies of micro-Raman
scattering and X-ray diffraction. In the matrix of these glasses, we observed SbSI
nanocrystalline inclusions. It has been shown that the sizes of crystalline inclusions are
dependent on the heat treatment regimes.
