For the first time, chalcogenide glasses from the GeSe2-In 2Te3-GeTe system are synthesized. Visual, X-ray diffraction, and electron microscopic investigations identify the glass-forming area, primarily located in the GeSe2-rich region.
Differential thermal analysis determines the characteristic temperatures of phase transformations, including the glass transition temperature (Tg), crystallization temperature (Tcr), and melting temperature (Tm). Hruby’s criterion is used to estimate the glass-forming ability (KG). The chalcogenide glasses’ density (d) and microhardness (HV) are measured. Compactness, elasticity modulus, and thermomechanical characteristics (micro-void volume (Vh) and formation energy (Eh)) are computed using the acquired properties. A thorough discussion and link between the glasses’ properties and composition are established.
