Abstract

The glass-formation regions in the quasi-ternary systems Ag2Se–(Zn, Cd, Hg)Se–GeSe2 were determined using the XRD data. The maximum content of the modifier ZnSe that could be introduced while preserving the glassy state is 10 mol.%, the respective value for CdSe is 12 mol.%. The largest region of the existence of glasses is observed in the mercury-containing system where it crosses the entire concentration triangle. The minimum content of the glass-forming component GeSe2 is 43 mol.%. Thermal properties of the glasses were characterized by the glass transition temperature, the crystallization temperature and the melting point of the crystallized alloy. The relationship of the thermal parameters and the fields of the primary and secondary crystallization of the respective equilibrium compositions was illustrated for the glasses of the mercury-containing system.
