C(t) was plotted from t = 0 once the system reached 500 K. Fig. depicts C(t) for models with other crystal planes. An increase in crystallinity was observed in all models, with C(t) increasing at a constant rate (zero-order reaction) during the initial stage of crystal growth until reaching saturation. The saturated values of C(t) ranged from 85.8 to 99.1%, as shown in Fig. .
