【摘要】 基于国内外工业副产石膏碳化法制备碳酸钙的研究现状,对比分析了直接碳化和间接碳化两类制备方法的优缺点,以转化效率和晶型形貌为碳酸钙质量控制参数,从反应条件、晶型控制剂及杂质离子多方面阐述对碳酸钙品质的影响,为实现该法工业化生产提供一定的理论支撑。更多还原

【Abstract】 Based on the research status of calcium carbonate production by industrial by-product gypsum carbonization at home and abroad,the advantages and disadvantages of both direct carbonation and indirect carbonation methods were compared.The conversion efficiency and crystal morphology were taken as the quality control parameters of calcium carbonate.The influences of reaction conditions,such as crystal shape,control agents and impurity ions,on the quality of calcium carbonate were discussed,and the theoretical support for the industrialization was provided.更多还原
