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. |
