摘要
Hydrophobic silicium dioxide (prepared by using pyrogen of the type flame oxidation or preferably by flame hydrolysis) doped with potassium of 0.000001-40 wt.%, is new. Independent claims are also included for: (1) preparations of surface-modified silicon dioxide; and (2) a silicone rubber comprising a hydrophobic agent of aerosol with potassium doped pyrogenic silicic acid as fillers.
