Abstract

In the present research paper, a computer programme is generated to obtain a theoretical non isothermal Differential Scanning Calorimetric (DSC) curve with the help of some parameters obtained through experimental isothermal DSC curves. To demonstrate the validity of this process, a comparison between the experimental and theoretical non-isothermal DSC curves of chalcogenide glass Se70Te24Cd6 has been carried out. A function 'F' composed of some parameters, obtained from non isothermal experimental curves, is used to calculate the Avrami exponent. The computed Avrami exponent agrees well with the reported experimental value.
