The crystal growth process of Mg Al CO3 hydrotalcite was then studied by adding different amounts of water to the resulting slurry during the crystallizing process. The initial 6 hours of the crystallization was found to be the key period controlling crystal growth. Adding 150 to 250mL of water to the reaction system at the beginning of crystallization affords Mg Al CO3 hydrotalcite with relatively small particle size and large aspect ratio.展开更多
