Impact of Rare Earth Elements on CaCO₃ Crystallization: Insights into Kinetics, Mechanisms, and Crystal Morphology.

ABSTRACT: This study investigated the crystallization kinetics and mechanisms of calcium carbonate (CaCO₃) in the presence of rare earth elements (REEs) including lanthanum (La), neodymium (Nd), and dysprosium (Dy). Through a comprehensive approach utilizing UV-vis spectrophotometry, powder X-ray diffraction, and high-resolution electron microscopy, we examined the effects of REEs on CaCO₃ growth from solution at varying concentrations and combinations of REEs. Our findings highlight that even trace amounts of REEs significantly decelerate the rate of CaCO₃ crystallization, also leading to alterations in crystal morphology and mechanisms of growth. The impact of REEs becomes more pronounced at higher concentrations and atomic mass, although the potential formation of
