Product Description

Product Description.
---------------------------------
Fumed silica, also known as fumed white carbon black, is a high-quality, fine chemical product. Produced through the hydrolysis of chlorosilane at elevated temperatures in a hydrogen and oxygen flame, this white, non-toxic, tasteless, amorphous material boasts an impressive range of applications. By meticulously adjusting processing conditions, our fumed silica features primary particle sizes ranging from 7 to 40 nm and a specific surface area between 50-400m2/g.
