| Abstract: | The starting materials were Soochow kaolin clay,which were calcined in the muffle furnace.The processed powder were then dissolved in HCl solution for some time.After the means of filtration and drying to the precursor were employed,the amorphous silica powder were obtained.The above products were collected for characterization of XRD and BET respectively,and the chemical constitution of that were also analyzed.The XRD patterns of the synthesized products showed that the powder synthesized were amorphous silica,chemical analysis datum indicated they have higher purity,BET showed the product was mesoporous materials with higher surface area. |
