Amorphous phases crystallize in a peculiar manner because both kinetic parameters (nucleation rate and growth rate of the crystalline phase) that control the process increase with increasing temperature. Thus, the amorphous phase converts to the crystalline one faster as the release rate of latent heat of crystallization increases (a system with a positive feedback). As a result, explosive crystallization can occur in which the conversion rate jumps by several orders of magnitude and then remains more or less constant [1].
