Article Preview

Glassy samples from the GeSe2-Sb2Te3-CdTe system are synthesized. The thermal characteristics (glass-transition Tg, crystallization Tcr and melting Tm temperatures) are determined using differential thermal analysis. On the base of the values of these temperatures the glass forming ability of the glasses is determined by the Hruby’s criterion. The main thermodynamic parameters (enthalpy ΔH and entropy ΔS alternation) of the crystallization are calculated. The values of the ΔH and ΔS vary within 21.196 – 98.625 kJ/mol and 33.91 – 170.93 J/(mol.K), respectively. The influence of the composition on the investigated characteristics is analysed.
