Abstract: measurements of differentially scanning calorimeter (DSC) under non isothermal technique (at heating rates (α) ranging from 2 to 32 K/min.) have been carried out. The (α) value is found to affect the characteristic temperatures (the temperature of glass transition (Tg ), the onset temperature of crystallization (Tc ) and the temperature of crystallized peak (Tp )) that helping us to investigate the Avrami’s exponent (n) and the activation energy for glass transition (Eg ) and crystallization (Ec ). The investigated results are discussed in terms of the chemical bond approach, the cohesive energy (CE) and the average heats of atomization (Hs ). The X- ray diffractograms confirmed the amorphous state of the as-prepared glasses.
