Glass formation in the As 2Te 3–As 2Se 3–SnTe system

Abstract

Chalcogenide glasses from the As 2Te 3–As 2Se 3–SnTe system were synthesized. The glass-forming region was determined by the help of visual, X-ray diffraction and electron microscopic analyses. The temperatures of phase transformations (the glass transition T g, crystallization T cr and melting T m) were measured. The glass-forming ability was evaluated according to Hruby's criteria K G. The correlation between composition and properties of the As 2Te 3–As 2Se 3–SnTe glasses was established and discussed.
