Fumed Silica: A Unique Nanostructured Silica Material Introduction to Fumed SilicaFumed silica, also known as pyrogenic silica, is a unique nanostructured form of silicon dioxide produced through flame hydrolysis of silanes. Unlike precipitated silica that uses a wet chemistry route, the production of fumed silica involves flame pyrolysis of silicon tetrachloride vapor or organosilicon compounds like hexamethyldisiloxane. This flame hydrolysis...
