Hydrophilic Fumed Silica Fumed silica, or pyrogenic silicon dioxide, is one kind of pure amorphous white inorganic powder that has a high specific surface area, nano-scale primary particle size, and a relatively high (among silica products) concentration of surface silanol groups. The properties of fumed silica can be chemically modified by reaction with these silanol groups.Synonyms: Pyrogenic silica, Fumed Silica Dispersion, Silicon Dioxide, Fumed SiO2
