描述了由氢氧化镁和二氧化碳制备碱式碳酸镁。该过程包括形成氢氧化镁浆料并向其中喷射二氧化碳气体。评估各种实验条件以获得导致羟基碳酸镁形成的条件。浆料 pH 值、浆料温度、干燥温度、干燥时间和 HCl 添加量是评估的条件。所得产物通过 XRD 进行鉴定，并通过 TG/DTA 研究其分解特性。从结果可以看出，实验参数对所得产品有显着影响。 (C) 2001 Elsevier Science B.V. 保留所有权利。
The preparation of a magnesium hydroxy carbonate from magnesium hydroxide and carbon dioxide is described. The procedure involves the formation of a magnesium hydroxide slurry and sparging CO2 gas through it. Various experimental conditions are evaluated in order to obtain the conditions that result in the formation of the magnesium hydroxy carbonate. Slurry pH, slurry temperature, drying temperature, drying time and HCl addition are the conditions that are evaluated. The products that are obtained are identified by XRD and its decomposition characteristics studied with TG/DTA. It is evident from the results obtained that the experimental parameters have a significant influence on the products obtained. (C) 2001 Elsevier Science B.V. All rights reserved.
