The production processes of white carbon black mainly include the gas phase method and the precipitation method. The gas phase method involves reacting raw materials such as silicon tetrachloride with oxygen at high temperatures to generate silica aerogel, which is then processed through aggregation, separation, and other steps to obtain white carbon black products. This method produces white carbon black with high purity and large specific surface area, but the production cost is relatively high. The precipitation method involves reacting sodium silicate with acid to generate silicic acid, which is then processed through precipitation, filtration, drying, and other processes to produce white carbon black. This method has lower costs and is suitable for large-scale production, although the purity and specific surface area of the product are slightly lower than those of the gas phase method. In recent years, with continuous technological advancements, production processes have been continuously optimized to improve product quality and reduce energy consumption.
