The present framework reports the structural, fundamental parameters, and crystallization kinetics of the melt-quenched As30Te64Ga6 chalcogenide glass. The energy dispersive X-ray analysis of the As30Te64Ga6 glassy system reveals that the constituent element ratio of the investigated bulk sample agrees with the nominal composition. Also, X-ray diffraction (XRD) and Differential Scanning Calorimetry (DSC) were used to characterize structural properties, and crystallization kinetics; respectively. Four characteristic temperatures related to various phenomena are observed in the investigated DSC traces. The first one is $$T_{g}$$ that corresponds to the glass transition temperature. The second one is ( $$T_{c1}$$ , and $$T_{c2}$$ ) that corresponds to the onset of the double crystallization temperatures. The third one ( $$T_{P1}$$ , and $$T_{P2}$$ ) identifies the double peak crystallization temperatures. The last characteristic temperature ( $$T_{m}$$ ) is the melting point. The XRD analysis indicates the amorphous structure of the as-prepared glassy alloy, while the annealed samples are polycrystalline. The crystallization kinetics of the As30Te64Ga6 bulk are studied under non-isothermal conditions. In addition, the values of various kinetic parameters such as the glass transition activation energy, weight stability standard, and Avrami exponent were determined. The activation energy of the crystallization process for As30Te64Ga6 glass alloy was calculated using classical methods. The results indicated that the rate of crystallization is related to thermal stability and the ability to form glass. Kinetic parameters have been estimated with some conventional methods and found to be dependent on heating rates (β).
