Nanotechnology continuously rises due to its potential applications. To control nano-materials design and microstructure, it is very essential to understand nucleation and crystalline growth in these materials. In this research contribution, crystallization kinetics and thermal behaviour of nano-crystalline Se_79-x Te₁₅In₆Pb _x (x=0, 1, 2, 4, 6, 8 and 10 at. wt%) chalcogenide alloys is analyzed through differential scanning calorimetry (DSC) process under non-isothermal conditions at four different heating rates; 5, 10, 15 and 20 C min⁻¹. The examined Se-Te-In-Pb nano-chalcogenide system is prepared through melt-quenching process. Characteristic temperatures namely glass transition temperature (T _g), onset crystallization temperature (To), peak temperature of crystallization (T _p) and melting temperature (T _m) show dependence on heating rate and composition. The various kinetic parameters such as activation energy of glass transition (E _g), activation energy of crystallization (E _c), reduced glass transition temperature (T _rg), Hruby number (K _gl), thermal stability parameters (S and H’) and fragility index (F _i) are analyzed for investigated Se-Te-In-Pb nano-crystalline system. Different empirical approaches are applied to determine the apparent glass transition activation energy (E _g) and crystallization activation energy (E _c).
