Lilia Aljihmani, Temenuga Hristova-Vasileva, Venceslav Vassilev

Chalcogenide glasses from the GeSe2-Sb2Te3 -CdTe are synthesized from the initial compounds by melt quenching technique. The density and the Vickers microhardness are determined. Using the density values the compactness C is calculated. The thermomechanical characteristics (microvoids volume Vh and energy for formation of amicro-void Eh), aswell as the elasticity modulus E of the glasses, are also calculated. A compositional dependence of the revealed properties is observed and discussed.
