Nano powder is also called nanoparticles, which generally refers to ultra-fine particles with a size between 1-100nm. Some people call it ultrafine particles. Its size is larger than atom clusters and smaller than ordinary particles. Calculated according to its size, assuming that each atom is 1 angstrom in size, it contains between 1000 and 1 billion atoms. It is smaller than normal biological cells and is about the size of a virus. The morphology of nanoparticles is spherical, plate, rod, horn, sponge, etc. The constituents of nanoparticles can be metals, oxides, or other various compounds.Luoyang Trunnano Tech Co., Ltd provide high purity nano-materials and elementary substance materials, including nano silicon powder,nano diamond powder,nano boron powder,nano graphite powder and other ultrafine metal materials.
