采用晶种静电吸附-诱导转化技术,成功地将选自工业废弃物粉煤灰的空心微 球转化为具有沸石/莫来石双层复合球壳结构的空心球,用XRD和SEM等手段对产物 进行了表征,并对球壳的转化机理进行了讨论。

关键词: 沸石, 粉煤灰, 吸附, X射线衍射分析, 扫描电子显微镜

A simple seeds electrostatic adsorption and induced conversion technology was presented to prepare hollow zeolite/mullite microspheres from the fly ash cenosphere, a solid waste with hollow structure selected from fly ash. The products have been characterized by using XRD and SEM and the conversion mechanism of the shells was discussed.

Key words: ZEOLITE, FLY ASH, ADSORPTION, XRD, SEM
