一种低比表面积气相二氧化硅，已经使用二氯二甲基硅烷 (DiMeDi) 对它进行了表面改性。

CAB-O-SIL TS-610 fumed silica is a low surface area fumed silica that has been surface modified with dimethyldichlorosilane. The treatment replaces some of the hydroxyls on the surface of the silica, resulting in increased hydrophobicity and very different performance than untreated silica.
CAB-O-SIL TS-610 fumed silica is characterized by:
• High purity
• Aggregated structure
• Submicron particle size
• Low bulk density
• Hydrophobic surface chemistry
