Discover the exceptional quality of our fumed silica, commonly known as fumed white carbon black. This white, non-toxic, tasteless, amorphous inorganic fine chemical is crafted through the hydrolysis of chlorosilane at high temperatures in a hydrogen and oxygen flame. By precisely adjusting process conditions, we produce fumed silica with primary particle sizes ranging from 7-40 nm and specific surface areas between 50-400 m²/g, ensuring unparalleled versatility and performance.
