Glass-formation and properties of phosphotellurite glasses through combinatorial method

Abstract

The compositional dependence of glass forming tendency and thermal properties was intensively investigated for P₂O₅-TeO₂-ZnO system with the aid of automatic sample preparation system including a batch-preparing apparatus and a multi-sample casting machine. The samples exhibited a variety of colors, such as transparent, yellow, wine red and brown depending on its composition. Analyses with scanning electron microscopy and X-ray photoelectron spectroscopy revealed that the reddish coloration is responsible for colloidal suspension of nano meter sized elemental Te particles.
