Using the melt-quenching method, the glass-formation region was investigated in the quasi-ternary system Ag₂S–HgS–GeS₂. The minimum content of the glass-forming element GeS₂ is 45 mol.%. Characteristic temperatures were determined for the glassy alloys and optical absorption spectra of the glasses were recorded. It was established that the optical bandgap energy varies from 1.7 to 2.3 eV.
