| Abstract: | The glass-forming region in the Se–Ge–Zn (I) and GeSe3–ZnSe–Ag2Se (II) systems are determined, as well as some physical and chemical properties (temperatures of softening, crystallization
and melting, density and microhardness). The glass-forming region in system I on the Se–Ge side (concentration limits 0–43%
Ge). The maximum solubility of Zn is around 6% (at Se:Ge = 9:1). The glass-forming region in system II lies on the side Ag2Se–GeSe3 (from 54 to 100% GeSe) and ZnSe–GeSe3 (from 78 to 100% GeSe3) of the Gibbs’ concentration triangle for GeSe3–ZnSe–Ag2Se.
