WebPrecipitated silica. Precipitated silica is an amorphous form of silica (silicon dioxide, SiO 2 ); it is a white, powdery material. Precipitated silica is produced by precipitation from a solution containing silicate salts. The three main classes of amorphous silica are pyrogenic silica, precipitated silica and silica gel. WebColloidal silica. We produce colloidal dispersions of silica particles in water under the trade name Köstrosol ®. The particles are made from high-purity alkali silicate. They are spherical and generally non-crosslinked and are hydroxylated at the surface. The reactivity of our colloidal silica can be modified and changed according to their ...
