Thermomechanical and structural characterization of GeSe2–Sb2Se3–ZnSe glasses

Abstract On the basis of thermal and physicochemical properties of multicomponent GeSe 2 –Sb 2 Se 3 –ZnSe glasses, several microstructural characteristics such as glass-forming ability ( K gl ), compactness ( C ), micro-voids volume ( V h ), their formation energy ( E h ), module of elasticity ( E ) and apparent activation energy of glass transition ( E a ) have been determined. Their compositional dependencies have shown that all these parameters increase at higher GeSe 2 content, remaining almost constant in the range of 63–72 mol% GeSe 2 . The distribution of the corresponding structural units has been discussed on the basis of Raman scattering data.
