And now , you may wonder what exactly fumed silica is. Let me explain to you.
Fumed silica, also known as colloidal silicon dioxide because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high surface area. Its structure results in viscosity-increasing,thixotropic behavior and excellent dispersion property. And Fumed silica is used in many fields like rubber, plastics, coatings, adhesives, food and drugs, CMP, heat- insulation materials and so on.
After all these you must have a good understanding about fumed silica now, it seems far away, but actually around us in many ways, let’s remember this white knight.
