New Chalcogenide Glasses in the GeSe2-As2Se3-CdTe System

Abstract

Glass-forming region in the GeSe2-As2Se3-CdTe system has been determined by visual, X-ray diffraction and electron microscope analyses. Glasses have been obtained in the GeSe2-rich region. Glass-formation has been situated wholly on the GeSe2- As2Se3 and partially on the GeSe2-CdTe and As2Se3-CdTe (0-15 Mol. % CdTe) sides in the Gibbs diagram. The maximal dissolution of CdTe in the glasses has been found up to 20 Mol. % CdTe. The temperatures of glass transition (Tg), crystallization (Tcr) and melting (Tm) of the glasses have been examined in the temperature range 20+950 degrees centigrade. Two exothermic effects have been registered at 440 and 565 degrees centigrade, which are connected with GeSe2 and CdTe crystallization, respectively. The endothermic effect observed at 680+20 degrees centigrade is related to the previous crystallized GeSe2 phase.
