摘要
Ultrafine SiO2 powders are prepared from sodium silicate and hydrochloric through the process of adding surfactant. The surface area of the powders were more than 1000 m(2)/g, and their pore size were 2.5 nm. The effects of the amount of surfactant and the concentration of reactants on the properties of products were studied. BET, XRD, IR, SEM, TEM and some other experiment method were used to investigate the other physical properties of the sample. (C) 1997 Elsevier Science S.A.
