Our Fumed Silica, commonly referred to as fumed white carbon black, is a high-grade, white, non-toxic, tasteless, amorphous inorganic fine chemical. Manufactured through the hydrolysis of chlorosilane at high temperatures in a hydrogen and oxygen flame, this premium material boasts adjustable process conditions. We produce fumed silica products with primary particle sizes ranging from 7-40 nm and specific surface areas between 50-400 m²/g, ensuring versatility for various industrial needs.
