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. TiO2/fumed silica porous ceramic material was used to prepare photocatalytic materials.
Features and Benefits
Has interesting thickening and thixotropic properties, and an enormous external surface area.
General description
Fumed silica may be synthesized by high temperature hydrolysis of SiCl4 in O2(N2)/H2 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.
Other Notes
Particle sizes are for primary particles, which form branched, chain-like aggregates a few tenths of a micron long.
