Abstract: Ultrafine SiO2 powders are prepared from water-glass and HCl through the process of addingsurfactant. The specific surface area of the powders was more than 1000m2/g, and their particlesize was about 0.1μm. The effects of the amount of surfactant and the concentration of reactantson the properties of products were studied. BET, XRD, TEM and some other experiment methodswere used to investigate the structure and other physical propertics of the sample.
Key words: SiO2 preparation, large specific surface area
