Exploring the Crystallization Tendency of Glass-Forming Liquid Indomethacin in the Tp Plane by Finding Different Iso-Invariant Points

Abstract: In this work, we examine in detail the crystallization tendency of the model glass-forming liquid indomethacin at varying thermodynamic conditions. To do that, we combine experimental results with predictions of the classical theories of nucleation and growth. We have considered changes in the crystallization rate k along iso-invariant curves located differently in the T–p phase diagram of the studied supercooled liquid. We include for the first time temperature and pressure conditions along which the thermody… Show more

“…Recently, based on the predictions of the classical theory of nucleation and crystal growth models, we have demonstrated that the overlapping of the N ( T ) and G ( T ) dependences is expected to expand with increasing pressure. Thus, accelerating the crystallization progress of the compressed glass-forming liquid …”

“…Thus, accelerating the crystallization progress of the compressed glass-forming liquid. 41 In the next step, we have compared the temperature and pressure dependences of the crystallization time (t cryst = 1/k) obtained along isobar 0.1 MPa and isotherms 243 and 253 K, as illustrated in Figure 3b. It is very interesting that obtained dependences considered either in T or p coordinates look very similar.…”

“…If the rate is controlled by a kinetic factor, which is invariant, and the driving force, then the question becomes whether the driving force is invariant. There is experimental evidence that this is nearly true [35,36] but the question has not been addressed theoretically yet. The isomorph perspective immediately suggests alternative ways to formulate the question: first, the appropriate curve to consider is one of constant reduced relaxation time τα = τ α ρ 1/3 T 1/2 ; second, the measured quantities should also be expressed in reduced units.…”

“…The motivation for the present work comes from recent experiments by Adrjanowicz et al [32][33][34][35][36] which have aimed to separately determine the kinetic and thermodynamic factors controlling crystallization of supercooled liquids by fixing the liquid's relaxation time τ α . Crystallization under pressure is of interest both scientifically and in the context of industrial applications, including materials science, food and pharmaceuticals.…”
