Aerosil is a fumed silica product developed in 1942 by Degussa AG in Germany.
Additional recommended knowledge
Aerosil is pure silicon dioxide, made from vaporized silicon tetrachloride, oxidized in high-temperature flame with H2 and O2. Aggregated amorphous nano-sized primary particles gives free flow to powder materials. It gives thickening effect and thixotropy by dispersing to liquid materials. Standard hydrophilic products are made of primary particles from 7 nm to 40 nm, and also these products are surface modified to hydrophobic.
