摘要
纳米碳酸钙的合成方法有多种，主要采用液相法，根据反应机理的不同又可将其划分为三种反应系统：Ｃａ（ＯＨ）２－Ｈ２Ｏ－ＣＯ２反应系统、Ｃａ２＋－Ｈ２Ｏ－ＣＯ３２－反应系统和Ｃａ２＋－Ｒ－ＣＯ３２－反应系统（Ｒ为有机介质），并对每种反应系统的特点、机理、控制因素等进行了分析。
Nano CaCO3 can be synthesized by many ways, while liquid phase method remains a main way. According to the differences in reaction mechanism, the method can be divided into three reaction systems: the system of Ca(OH)2H2OCO2, the system of Ca2+H2OCO2, and the system of Ca2+RCO32- in which R is an organic medium. The characteristic, mechanism, controlled conditions etc are analysed for each system.
