The properties of many sulfide and selenide glasses correspond closely to related oxide systems; this correspondence can be correlated with the ratios of the valences and of the radii of the anions and cations. The analogy of chalcogenides to oxides in phase separation behavior is striking. Systematic substitutions prove the validity of Zachariasen's rules for covalent materials. The glass‐former cations which tend to polymerize during cooling have a coordination number of 3 or 4. The comparison has been extended to network modifiers among the sulfides and selenides.
