摘要
通过综述球霰石碳酸钙的结构、合成和表征方法,阐明球霰石碳酸钙是一种热力学上的不稳定性相。具有功能基团的有机高分子、功能蛋白质以及无机镁离子等添加剂对它有一定的稳定作用,抑制它的转化;但是在一定条件下它将转化成结晶态的碳酸钙。球霰石碳酸钙具有较大的比表面积、较高的溶解性和分散性能以及较小的比重,正是因为这些特性应用于工业领域能够改善目标产品的物理性能、填充性能和印刷性能,以及生物采用它作为机体重要的结构材料。通过对球霰石碳酸钙的研究,能够更加深入地了解生物矿化的机理,更好地仿生合成和制备各种功能材料。
The structure,synthesis and characterization of vaterite calcium carbonate are introduced.The amorphous phase is thermodynamically metastable.However,its stability and transformation into the crystallized calcium carbonates can be regulated by additives e.g.functional polymer,protein and inorganic ions etc.Since the vaterite calcium carbonate has relatively large surface area,the higher solubility and dispersion performance and the smaller proportion,these properties can uniquely improve physical property,filling property and printing performance about the target products in the industrial field,and biologically it can be used as an important structural material.The studies of vaterite calcium carbonate can improve the understanding of the mechanisms of biomineralization and deep understanding of the biomimetic preparation of functional materials.
