Product Description

Product Description.
---------------------------------
Our fumed silica, also known as fumed white carbon black, is a pristine, non-toxic, and tasteless amorphous inorganic fine chemical. This superior product is meticulously crafted by hydrolyzing chlorosilane at high temperatures within a hydrogen and oxygen flame, resulting in an exceptional white powder. By fine-tuning our process conditions, we offer fumed silica with a primary particle size ranging from 7-40 nm and a specific surface area spanning 50-400 m2/g.
