产品介绍	一般描述气相二氧化硅可以通过在O 2 （N 2 ）/H 2 火焰中，SiCl 4 的高温水解来合成。它本质上是无定形状态，并且具有非常高的比表面积。无定形二氧化硅的微滴可熔合成分支并形成链状聚集体。应用在人肝癌细胞HuH-7和人肝细胞系HepG2的Taqman测定中，气相二氧化硅可用于减少脂质和激素。环氧化天然橡胶/气相二氧化硅复合材料的制备已有报道。Gemini表面活性剂C12-s-C122Br与热解法二氧化硅的水悬浮液的相互作用已有研究。可制备有机粘土增强的气相二氧化硅基纳米复合材料。TiO 2 /气相二氧化硅多孔陶瓷材料可用于制备光催化材料。其他说明粒径是针对初级粒子，它们形成支链状聚集体，仅长零点几微米。 General Description Fumed silica may be synthesized by high temperature hydrolysis of SiCl 4 in O 2 (N 2 )/H 2 flame. It is amorphous in nature and possesses very high specific area. The micro droplets of amorphous silica fuse into a branch and form a chain like agglomerate. Application Fumed silica is used to deplete lipids and hormones in Taqman assays of human hepatoma cells HuH-7 and human liver cell line HepG2. Preparation of epoxidized natural rubber/fumed silica composites have been reported. Interaction of Gemini surfactant C12-s-C122Br with aqueous suspension of fumed silica has been studied. Fumed silica based nanocomposites reinforced with organo clay may be prepared. TiO 2 /fumed silica porous ceramic material was used to prepare photocatalytic materials. Other Notes Particle sizes are for primary particles, which form branched, chain-like aggregates a few tenths of a micron long.
