Our premium Fumed Silica, also known as fumed white carbon black, is an exquisite, non-toxic, and tasteless amorphous inorganic fine chemical product. It is meticulously crafted through the hydrolysis of chlorosilane at elevated temperatures within a hydrogen and oxygen flame. By tweaking process parameters, we are able to produce fumed silica with primary particle sizes ranging from 7-40 nm and a specific surface area between 50-400m²/g.
