Chromium Oxide Nanoparticles (Cr2O3) Applications:
Chromium(III) oxide is the inorganic compound of the formula Cr2O3. It is one of principal oxides of chromium and is used as a pigment. In nature, it occurs as the rare mineral eskolaite. Because of its considerable stability, chromia is commonly used pigment and was originally called viridian. It is used in paints, inks, and glasses. It is the colourant in "chrome green" and "institutional green." Chromium(III) oxide is the precursor to the magnetic pigment chromium dioxide, according to the following reaction: Cr2O3 + 3 CrO3 → 5 CrO2 + O2. It is one of the materials that are used when polishing the edges of knives on a piece of leather (also called stropping).
