Mainly used for rubber intensifier and packing, its consumption is about half of rubber rubber consumption of carbon black with carbon black 94% of the total, with approximately 60% for tyre manufacture. In addition, also used for printing ink, paint and plastic colorants and plastic products BingBiJi of ultraviolet light. In many other products, such as electrode, dry, resistors, explosives, cosmetics, and polishing compound, it is also important fertilizer.
