Abstract The hydrogen distillation of glasses of composition Se-40As, Se-20Ge and Se-30Ge-15As from elemental raw materials in a 200 g scale horizontal tube furnace and in a 1.5kg capacity vertical silica still and condenser, is described. The results demonstrate that inclusion-free and oxide-free glass can be prepared from cheap impure arsenic and selenium raw. materials in the vertical still. The germanium selenide binary glass cannot be prepared by this technique due to fractionation into selenium glass and germanium selenide crystalline products. The ternary composition is capable of being manufactured by this process but an unacceptably high loss of arsenic and selenium can occur.
