“…2. network the formation of the Cd 4 GeSe 2 Te 4 and Sb 2 SeTe 2 phases is possible, which is proven by XRD [5]. This approach leads to densification of the structure with the increase of the CdTe content at m=0.05.…”

“…The crystallization temperature of p.4 most likely refers to the crystallization of the Sb 2 SeTe 2 phase [10]. The phase composition of the samples after crystallization is investigated in our previous work [5] and the crystallization of the following phases is established: GeSe [11], Sb 2 SeTe 2 [10], GeSe 2 [12] and Cd 4 GeSe 2 Te 4 , isostructural to Cd 4 GeSe 6 [9].…”

“…The glass forming region in the GeSe 2 -Sb 2 Te 3 -CdTe system (Fig. 1) lies partially on the GeSe 2 -Sb 2 Te 3 (from 0 to 32.5 mol % Sb 2 Te 3 ) and the GeSe 2 -CdTe (from 0 to 27 mol % CdTe) sides [5]. A small crystalline area is observed in the concentration interval 5-12 mol % CdTe with maximum solubility of Sb 2 Te 3 in it of about 2 mol %.…”

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.
