Gas phase white carbon is one of the most important high-tech ultra-fine inorganic new materials. Because of its small particle size, it has large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion, thermal resistance, resistance and other special properties. With its superior stability, reinforcement, thickening and thixotropy, it has unique characteristics in many disciplines and fields and plays an irreplaceable role. Gas phase white carbon black, commonly known as "nano white carbon black", is widely used in various industries as an additive, catalyst carrier, petrochemical industry, decolorizing agent, matting agent, rubber reinforcing agent, plastic filling agent, ink thickening agent, metal soft polishing agent, insulation and thermal insulation filler, high-grade daily cosmetics filler and spraying materials, medicine, environmental protection and other fields. It also provides new material basis and technical guarantee for the development of relevant industrial fields. Because of its special functions in magnetism, catalysis, light absorption, thermal resistance and melting point compared with conventional materials, it has received great attention.
