Abstract

This paper reports the isothermal differential scanning calorimeter (DSC) method used to study the crystallization kinetics of aluminum fluoride glass. The effective activation energy of crystallization (ΔEa/n) was evaluated from the DSC curves using the Johnson‐Mehl‐Avrami equation. The value of the effective activation energy (Ea/n = 113.3 kJ/mol) found from the isothermal DSC curves was slightly higher than that obtained previously with the non‐isothermal DSC method (ΔEc/n = 108.1 kJ/mol). It turns out that both methods can be used in this case.
