粉煤灰空心微珠沸石化制备复合空心球
Zeolitization of Fly Ash Cenosphere to Create Hollow Composite Spheres
【摘要】 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珠转化为具有沸石 /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 .
【Abstract】 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.
