摘要:

無定形碳酸鈣在具有多級結構和優異力學性能的碳酸鈣礦物的形成過程中起著至關重要的作用。生物體可以非常精確地調控無定形碳酸鈣的結晶轉化過程，而化學合成的無定形碳酸鈣通常很不穩定。因此，從化學的角度研究無定形碳酸鈣的穩定機理以及無定形碳酸鈣結晶轉化過程，對于理解以無定形物相為前驅體的生物礦物形成過程具有非常重要的意義。綜述了無定形碳酸鈣的本征特性，以及環境因素和添加劑對其穩定性和結晶轉化的影響，闡述了無定形碳酸鈣在晶體生長過程中的作用，討論了該領域對材料結構和特性調控方面的啟示。

Abstract:

Amorphous calcium carbonate (ACC) plays a very important role in the formation of calcium carbonate minerals with a multi-level hierarchical structure and excellent mechanical properties. Organisms can accurately regulate the crystallization process of ACC, while synthetic ACC is usually very unstable. Therefore, studying the stabilization mechanism of ACC and the crystallization process of ACC from a chemical perspective is of great significance for understanding the formation process of biominerals via an amorphous precursor. This article summarizes the intrinsic properties of ACC, and the influence of environmental conditions and additives on crystallization process, explains the role of ACC during the crystallization process, and discusses the implications of this field on the regulation of material structure and properties.
