| Abstract: | Fiber-like SiO2 was prepared by a hydrochloric acid insitu acidification method,where wollastonites from Fengjiashan,Hubei province,were used as the raw materials.The effects of reaction conditions on the reaction degree and the product composition were discussed.The structures of the products were characterized by SEM and XRD.The results showed that the products could been categorized to two kinds of subjects,one was amorphous SiO2 and the other preserved the fiber-like wollastonite structure,surface holes were more fluffy,its composition was amorphous SiO2and a litter SiO2crystal.The reaction degree of combination autoclave reaction bath is more thoroughly,and the direct product has a higher content of amorphous SiO2. |
