=T8/Tm and Kh = (-Tg)/(Tm-),
glass stability parameters such as Kw = (Txh-Tg)/Tm,
ΔT = Txh-Tg and Kll
= Txh/(Tg+Tm) and the degree of
undercooling ΔTr = (Tm-T)/Tm are analysed
for glasses of the ternary system Sb2S3-As2S3-Sb2Te3
as function of the As2S3 concentration. These parameters
are formulated by different combinations of the following characteristic Differential
Scanning Calorimetry (DSC) temperatures: the glass transition temperature (Tg),
the onset crystallization temperature (Txh), the peak
crystallization temperature (Tch) and the melting temperature
(Tm). Variations of the above parameters indicate that the studied
glasses can vitrify easily and become increasingly stable when the concentration
of As2S3 increases. Good correlations between ΔTr
and Kh and between ΔTr and parameters (Kw,
ΔT and Kll), are found implying a low frequency of homogeneous
nucleation in the thermally stable glasses. The degree of undercooling ΔTr
is an important parameter for the glass forming ability and the glass stability
of Sb2S3-Sb2Te3-As2S3
glasses.]]>Aljihmani, L., V. Vassilev and P. Petkov,2003511871192Avramov, I., E.D. Zanotto and M.O. Prado,2003320920Chol-Lyong, J., Xia Lei, D. Ding and D.
