Abstract:

Two experimental approaches were used in attempts to compound non- oxide chalcogenide glasses based on the transition element titanium. The first was an open-chamber method in which the reactants were rapidly heated using a high-temperature dc arc. Heavy losses of volatile constituents during the arcing process prevented this method from producing a homogeneous melt. In the second method the reactants were sealed in a quartz vial which was supported by either a boron nitride or a graphite chamber. Compounding the Ti-V-Te system at 1600 to 1700C produced a homogeneous melt, but glasses did not form when the melt was quenched. Selenium glasses containing the transition elements nickel, zinc, and manganese were formed but none had physical properties significantly better than selenium glasses evaluated previously. No tellurium-based glasses containing transition elements formed.
