Nonisothermal Crystallization Kinetics by DSC: Practical Overview

Providing a minimum of theory, this review focuses on practical aspects analyzing the kinetics nonisothermal crystallization as measured with differential scanning calorimetry (DSC). It is noted that kinetic analysis dominated by approaches based Avrami and Arrhenius equations. Crystallization should not be considered synonymous model, whose applications are subject to very restrictive assumptions. The equation can serve only narrow temperature range approximation actual bell-shaped dependence rate. Tests applicability both equations discussed. Most traditional methods tend offer unsophisticated treatments, limited either glass or melt crystallization. Differential flexible integral isoconversional applicable because they accurately approximate rate series equations, each which corresponds its own interval. resulting activation energy parameterized in terms Turnbull–Fisher Hoffman–Lauritzen theories, parameters obtained meaningfully interpreted used for simulations.
