| Popis: | Structural and adsorptive characteristics of unmodified and modified silica gels Davisil 633 and 643, and fumed silica Cab—O—Sil HS-5, were analyzed on the basis of nitrogen adsorption isotherms. The properties of aqueous suspensions of the initial and modified fumed silicas were also studied. Deviation of the pore shape from simple models, cylindrical pores for silica gels and gaps between spherical particles for fumed silica, increases for modified silicas. |
