Nanometer Products refer to new materials consisting of particles having a particle size of 1 to 100nm. Because of its small size, large surface size and quantum size effect, it has the special properties of conventional coarse grain material, which has obvious application prospect in light absorption, sensitivity, catalysis and other functional characteristics. So that nano products research into a hot material science.

In recent years, China has made remarkable achievements in the preparation, characterization, performance and theoretical research of nano materials. It has formed some research groups and bases, and has a place in the field of international nano materials research. The preparation of Nano Powder in nano preparation sience has developed rapidly due to its remarkable application prospect.
