摘要: 球霰石型碳酸钙具有独特的物理、化学、生物和机械特性,在日用、生物医药和新材料等领域极具应用前景。然而,球霰石型碳酸钙是碳酸钙三种无水晶体中热力学性能最不稳定的一种,极易转换为文石型或方解石型碳酸钙,尤其是在潮湿环境或者水溶液中,这就导致球霰石型碳酸钙在生产、加工和应用方面存在诸多困难。因此,球霰石型碳酸钙的稳定制备一直是碳酸钙领域的热点之一。本文综述了近些年来有关球霰石型碳酸钙的稳定调控制备方法,包括碳化法、复分解法、生物矿化法、模板法等,并将这些方法按照制备原理和实施工艺进行了分类归纳,阐述了它们的优缺点及应用前景,分析了在调控制备过程中各项因素的影响规律,旨在为实现工业上球霰石型碳酸钙的稳定制备提供理论参考。

Abstract: Vaterite-type calcium carbonate has unique physical, chemical, biological and mechanical properties, and has great application prospects in the fields of daily use, biological medicine, building materials and new materials. However, vaterite-type calcium carbonate is the most unstable thermodynamically stable one among the three anhydrous calcium carbonate crystals, and it is easily converted into aragonite-type or calcite-type calcium carbonate, especially in humid environments or aqueous solutions, this conversion is more likely to occur. This results in many difficulties in the production, processing and application of vaterite-type calcium carbonate. Therefore, the stable preparation method of vaterite-type calcium carbonate has always been one of the research hotspots in the field of calcium carbonate. In this paper, the research methods for the stable regulation and preparation of vaterite-type calcium carbonate in recent years are reviewed, including carbonization method, complex decomposition method, biomineralization method, template method and so on. According to the preparation principle and implementation process, these methods are classified and summarized, their advantages, disadvantages and application prospects are expounded, and the influence laws of various technological factors in the control and preparation process are analyzed. The purpose of this article is to provide practical and theoretical references for the realization of the stable preparation of vaterite-type calcium carbonate in industry.
