摘要:

纳米碳酸钙作为一种通用材料,具有广泛的应用前景和市场需求,近年来备受关注。然而,由于纳米碳酸钙晶型的多样性,导致其在不同领域具备不同的应用潜力。因此,对不同晶型纳米碳酸钙的制备方法、生长影响因素及形成机制进行了深入研究,并且有目标地制备特定晶型产品已成为当前研究的焦点。首先概述了纳米碳酸钙结构,并总结了两种常见制备方法的优缺点和机理;其次重点阐述了晶型控制剂和制备工艺对纳米碳酸钙晶型调控方面的研究进展,并介绍了两种反应器能够增强溶液间微观混合效果,从而大幅提高整体反应效率;最后综述了纳米碳酸钙结晶过程同时受晶体成核和晶体生长共同控制。通过研究这两个结晶过程可以更好地理解内在机理,最终实现晶型和形貌的精确调控。

Abstract:

As a general material,nano calcium carbonate has a wide range of application prospects and market demand,and has attracted much attention in recent years.However,due to the diversity of crystal forms of nano-calcium carbonate,it has different application potential in different fields.Therefore,the preparation methods,growth influencing factors and formation mechanism of nano-calcium carbonate with different crystal forms have been studied in depth,and the targeted preparation of specific crystal products has become the focus of current research.In this paper,the structure of nano-calcium carbonate was summarized firstly,and the advantages,disadvantages and mechanisms of two common preparation methods were summarized.Secondly,the research progress of crystal form control agent and preparation process on the regulation of nano-calcium carbonate crystal form was emphasized.It was also described that the two reactors were able to enhance the microscopic mixing effect between solutions,thus significantly improving the overall reaction efficiency.Finally,it was reviewed that the crystallization process of nano-calcium carbonate was controlled by both crystal nucleation and growth.By studying these two crystallization processes,the regulation mechanism could be better understood,and finally the precise regulation of crystal form and morphology could be achieved.

Key words: nano calcium carbonate, crystal controlling, synthesis mechanism, crystallization guiding agent
