Abstract

Cadmium (Cd) doping has enhanced the mineral properties, glass mesh, and movement traits of the Se₉₀Te₁₀ glassy alloy. The (Se₉₀Te₁₀)₉₅Cd₅ alloy has a strength 0.032 kN, accompanied by limited ductility, and displays brittle fracture behavior typical of amorphous chalcogenide glasses. (DSC) at varying heating rates was employed to examine the crystallization kinetics in bulk Se₉₀Te₁₀ and (Se₉₀Te₁₀)₉₅Cd₅ compositions; X-ray diffraction analysis was utilized to identify the crystalline structure of Se₉₀Te₁₀ and (Se₉₀Te₁₀)₉₅Cd₅, confirming the non-crystalline nature of both materials. Various kinetic frameworks were developed utilizing activation energies for glass transition and crystallization processes. “The Kissinger equation” was employed to determine the effective crystallization activation energy (Ec). “The Sestak-Berggren” approach was applied to analyze DSC crystallization data due to its compatibility with the observed experimental results. Therefore, elevated heating rates were determined to be suitable when combined with the Johnson-Mehl-Avrami framework, while the crystallization characteristics of bulk Se₉₀Te₁₀ and (Se₉₀Te₁₀)₉₅Cd₅ compositions under different heating conditions were investigated using DSC analysis.
