Chromium Nitrate (Cr(NO3)3) Nanoparticles – Properties, Applications

Nanoparticles are used in a number of critical applications in the field of biomedicine, cosmetics, optics and electronics, which were earlier not possible using the elements in their native states. This article will look into the properties and applications of chromium nitrate nanoparticles.

Chromium nitrate (Cr(NO3)3) is a crystalline chromium compound highly soluble in water. Some of the synonyms of chromium nitrate are chromium trinitrate nonahydrate, chromic nitrate nonahydrate, chromic nitrate and chromium nitrate nonahydrate. Chromium belongs to Block D, Period 4 while nitrogen belongs to Block P, Period 2 of the periodic table.
