Nano-silicon dioxide is an inorganic chemical material, commonly known as white carbon black. Because it is ultra-fine nano-scale, the size range is from 1 to 100nm, so it has many unique properties, such as optical properties against ultraviolet rays, which can improve the aging resistance, strength and chemical resistance of other materials. It is very versatile. Nano-sized silica is amorphous white powder, non-toxic, odorless, non-polluting, micro-structured spherical, flocculent and reticulated quasi-particle structure, molecular formula and structural formula is SiO2, insoluble in water.
Nano is a scale of 10-9 meters. Nanomaterials refer to a range of at least one dimension in the three-dimensional space, that is, in the range of 1 to 100 nanometers. Nanomaterials have small size effects, surface effects and macroscopic quantum tunneling effects, thus exhibiting many unique properties, and have broad application prospects in catalysis, filtering, light absorption, magnetic media and new materials.
