| Abstract: | Ultrafine powder of aluminum oxide was successfully prepared by using of fly ash.It also presented the process of Using C 2S(2CaO.SiO 2) crystal phase transfer and self powder,high efficient disperser——carbonize methods for the preparation of aluminum powder from fly ash,and confirmed the optimum process condition of abstracting aluminum oxide from fly ash.This has opened a new way for the high value usage of fly ash. |
