摘　　要：晶型碳酸盐具有特殊形貌和较窄的粒径分布,在油墨、电子、军事等领域有着重要应用。碳化法因其制备工艺简单、过程易于控制、成本低廉,可制备具有特定物理性质的金属化合物,成为制备晶型碳酸盐的重要工艺。概述了现有的碳化技术,按照CO_(2)鼓泡类型分为直接鼓泡法和微泡强化法;阐述了碳化过程的影响因素,主要影响因素有碳化温度、CO_(2)流速和浓度、料液浓度、添加剂、搅拌速度及pH值;最后综述了碳化法的典型应用领域,主要包括制备碳酸钙、纳米白炭黑、碱式碳酸镁及碳酸稀土等,并对碳化法制备晶型碳酸盐未来发展前景和趋势进行了展望。Crystalline carbonates,characterized by their distinctive morphologies and narrow particle size distributions,hold significant applications in fields such as ink manufacturing,electronics,and military technologies.Carbonation methods have emerged as a critical process for synthesizing crystalline carbonates due to their simplicity,controllability,low cost,and ability to produce metal compounds with tailored physical properties.This review systematically outlines existing carbonation technologies,categorizing them into direct bubbling and microbubble-enhanced methods based on CO_(2)introduction strategies.Key factors influencing the carbonation process are elaborated,including carbonation temperature,CO_(2)flow rate and concentration,solution concentration,additives,stirring speed,and pH values.Furthermore,the review highlights typical applications of carbonation techniques,such as the preparation of calcium carbonate,nano-silica,basic magnesium carbonate,and rare-earth carbonates.Finally,future prospects and trends in carbonation-based synthesis of crystalline carbonates are discussed.
