The glass‐forming regions were investigated for pseudobinary systems of the composition X M m Se n ‐(1– X )Ge 1.5 As 0.5 Se 3 (M m Se n =PbSe, CdSe, BaSe, ZnSe, or La 2 Se 3 ). Systems containing PbSe, CdSe, and BaSe contain substantial regions of glass formation, and differential scanning calorimetry, electron microscopy, and water corrosion tests were used to characterize these glasses. The glasses were generally phase‐separated, and the available data suggest that for PbSe melts the region of liquid‐liquid immiscibility spans almost the entire pseudobinary composition range. A few studies of glass formation were conducted for CdSe‐M m Se n ‐Ge 1.5 As 0.5 Se 3 pseudoternary and M m Se n ‐GeSe 2 binary melts.
