摘要: ABSTRACT OF THE DISCLOSURE A stable silica sol has an SiO2 concentration of 40 % or less. The contains amorphous colloidal particles each having a particle size D1 from to 500 my, as measured by the dynamic light-scattering method, being dispersed in liquid medium. Each shape elongated only one plane and uniform thickness mµ along elongation. degree elongation is 5 30 terms ratio D1/D2, where size, D2 mµ, calculated formula = 2720/S S specific surface area (m2/g) be nitrogen gas-adsorbing method (BET). Also disclosed for preparing sol, 20 diameter 300 my. Further Dl/D2 30.
