Hydrophobic Fumed Silica
Fumed silica, or pyrogenic silica, colloidal silicon dioxide, is amorphous white inorganic powder which has 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. -
