摘　　要：碳酸钙是一种重要的无机功能材料,广泛应用于工业生产领域。随着世界工业的快速发展,对高性能轻质碳酸钙(PCC)的需求不断增长。化学法是制备高性能轻质碳酸钙功能性产品的唯一途径,本文介绍了方解石、文石和球霰石3种晶型碳酸钙的特点,概述了Ca^(2+)-H_(2)O-CO_(3)^(2-)体系、Ca^(2+)-H_(2)O-CO_(2)体系和Ca^(2+)-R-CO_(3)^(2-)(R为有机介质)体系等3种化学法合成轻质碳酸钙制备体系的研究现状,综述了无机离子、可溶性共聚物和生物大分子这3类主要添加剂在化学法制备轻质碳酸钙中的作用。针对我国对高性能轻质碳酸钙产品严重依赖进口的现状,指出了轻质碳酸钙未来的重点发展方向。Calcium carbonate is an important inorganic functional material that has been widely used in the field of industrial production.With the rapid development of global industry,the demand for high-performance lightweight calcium carbonate(PCC)is constantly increasing.The chemical method is the only way to prepare high-performance functional products of light calcium carbonate.This paper introduces the characteristics of three crystal forms of cal-cium carbonate:calcite,aragonite,and vaterite,and summarizes the research status of three chemical methods for synthesizing light calcium carbonate,including Ca^(2+)-H_(2)O-CO_(3)^(2-)system,Ca^(2+)-H_(2)O-CO_(2)system,and Ca^(2+)-R-CO_(3)^(2-)(R is an organic medium)system.The roles of three main additives,inorganic ions,soluble copolymers,and biomacromolecules,in the chemical synthesis of light calcium carbonate are summarized.In response to the serious dependence on imported high-performance light calcium carbonate products in China,the key development directions for light calcium carbonate in the future are pointed out.
