    Fumed Silica Powder (SiO2) - Reade Advanced Materials

    Fumed silica is an extremely small particle with enormous surface area, high purity, and a tendency to form chains in the chemical manufacturing process. Particles are formed by injecting chlorosilanes, such as silicon tetrachloride, into a flame of hydrogen and air. The ensuring reaction produces fumed silica and hydrogen chloride.
