Product Description

 

Product Description

Fumed silica, commonly referred to as fumed white carbon black, is a premium, non-toxic, tasteless, amorphous inorganic fine chemical. It is meticulously crafted through the high-temperature hydrolysis of chlorosilane in a hydrogen and oxygen flame. By precisely adjusting the process conditions, our fumed silica can vary in primary particle size from 7 to 40 nm and boast a specific surface area ranging from 50 to 400 m²/g.
