Nano silica is a kind of inorganic chemical material. It is amorphous white powder, non-toxic, tasteless, pollution-free, spherical microstructure, flocculent, and reticulate quasi-granular structure.
Nano silica has many properties that conventional materials do not have. The particle size distribution of nano silica is very narrow, most of which are within 100 nm, with many micropores and large specific surface area.
High purity nano alumina is applied to the positive and negative diaphragm of lithium battery as a ceramic coating, which plays the role of heat resistance, high temperature resistance and insulation, so as to prevent the power battery from short circuit
Nano zinc oxide can be used in surface coating products and used in space vehicles, and there has been research on the application of nano-materials in industry, such as ceramic and rubber industry.
