    摘要: Surface-modified silicas Surface-modified, highly structured, potassium oxide-doped silicas, characterized by BET surface area, m2/g: 25-400 average primary particle size, nm: 5-50 pH: 3-10 carbon content, % by weight: 0.1-10 potassium oxide content, % by weight: 0.000001-40 are prepared by subjecting a potassium oxide-doped silica to surface modification. It can be used as a filler in silicone rubber compositions.
