I HN series of silicon oxide nanoparticles (nano-silica) of the average particle size of 10 - 30nm, purity of 99.5% - 99.9%, with a small particle size, pore number, surface area, surface hydroxyl content, ultraviolet, visible and infrared reflectivity and other characteristics. Nano-materials have four effects: small size effect, quantum size effect, surface effect and macroscopic quantum tunneling effect, which has traditional materials do not have unique physical, chemical, optical and other properties. Widely used in rubber, plastics, electronics, paint, ceramic (enamel) porcelain, plaster, batteries, paints, adhesives, cosmetics, glass, steel, fiber, glass, environmental protection and other areas. 
 Nano-silica is extremely important to new materials technology of ultra-fine inorganic, because of its small size, so large surface area and strong adsorption, the surface can be large, high chemical purity, dispersion properties, thermal resistance, specific resistance and other aspects of performance, with its superior stability, reinforcement, thickening and thixotropy, in many disciplines and areas of unique features, the irreplaceable role. Nano-silica commonly known as "ultra fine white carbon black", widely used in various industries as an additive, catalyst support, bleaching agents, matting agents, rubber reinforcing agent, plastic filler, printing ink thickener, soft metal polishing agent, insulation insulation filler, filler and oil advanced cosmetics industry, coating materials, medicine, environmental protection and other areas. And for the development of related industries based on new materials and technical assurance. Because of its magnetic, catalytic, optical absorption, thermal resistance and melting point, etc. Compared with the conventional materials show specific features, so to get people to great weight.
