The Research of Synthetic Porous Silica by Wollastonite and Progress in Application

This paper is to summarize and analyze the progress in synthetic porous silica by wollastonite and surveys its application. The porous silica was prepared by wollastonite with hydrochloric acid and applied in the field of silastic, catalyst support, gas purification and absorption. Compared with other method, the method of preparing porous silicon with wollastonite not only was low-cost, played the advantages of mineral resources and friendly environment, but also had outstanding acidproof, bearing the alkali, the thermostahle performance, the good electric insulation and the scattered performance, it was new type amorphous solidstate materials with very important value and broad prospects of application.
