Gaseous white carbon black, a nano-scale white powder produced by the high-temperature hydrolysis of silicon halides (mainly silicon tetrachloride and methyltrichlorosilane) in a hydrogen-oxygen flame. Its scientific name is fumed silica or aerosol silica. It is mainly used as a reinforcing filler and a multifunctional additive to make a truly industrialized nano material worldwide.

The product is an artificial synthetic amorphous white fluid powder with a strict particle size distribution of various specific surface areas and volumes. This product is a white, loose, amorphous, non-toxic, tasteless, odorless, non-polluting non-metal oxide. Its primary particle size is between 7 and 80 nm, and its specific surface area is generally greater than 100 m2 / g. Due to its nano-effect, it exhibits excellent properties of reinforcement, thickening, thixotropy, insulation, matting, and anti-sagging in materials, so it is widely used in polymer industries such as rubber, plastics, coatings, adhesives, sealants, etc. field
