Silicon dioxide is a kind of super fine precipitated silicon dioxide(known as silica) made by special processing technology. It has excellent reinforcement and dispersion, many years of production practice shows that it can replace fully or partly of expensive fumed silica which has greatly reduce customers' production cost.

Precipitated silica, also called ‘white carbon black‘, is an amorphous form of silica (silicon dioxide, SiO2); it is a white, powdery material. Precipitated silica is produced by precipitation from a solution containing silicate salts.
