Uses of Chromium

Choromium was discovered by French Chemist Louis-Nicolas Vauquelin in1797 and named from the greek world chroma, meaning color this was an appropriate choice because all of the compounts of chromium arecolored. One of the principal uses or chromium compunds is in the manufacture or pigments. Chromium oride (r2o3) for example is the most stable green used for cloring cements, plasters.
