Fumed silica is produced by hydrogen-oxygen flame combustion with water vapor (H2O) up to 1100~1800℃ to rapidly hydrolyze the above-mentioned vaporized chlorosilanes, and all under gas phase conditions, produce nano-scale (7~40nm) native The particle size silica particles are aggregated and deacidified to obtain fumed silica. Because of its large specific surface area and a large number of surface hydroxyl structures, it shows great reinforcement, thickening, thixotropy and anti-settling properties in the colloid, making its application very wide.
