摘要

Electronegativity difference Δx, atomic size parameter δ and width of supercooled liquid region (ΔTx = T x - Tg, where Tx is the onset crystallization temperature and Tg the glass transition temperature) are analysed for glasses of the ternary system Sb_2S_(3-)As_2S _(3-)Sb_2Te_3 as a function of arsenic atomic percentage. Correlation is investigated between the two bonds parameters (Δx and δ) and the width of supercooled liquid region ΔTx (which is generally reliable in estimating the stability against the crystallization of the glasses). It is found that this width of supercooled liquid region of the glasses in Sb_2S_(3-)As _2S_(3-)Sb_2Te_3 system depends on electronegativity difference and atomic size parameter.
