Chromium trioxide, chemical formula CrO3, is widely used for electroplating, oxidant, catalyst, wood preservative and production of other chromium salt products.
Chromium trioxide is an inorganic compound with the formula CrO3. It is the acidic anhydride of chromic acid, and is sometimes marketed under the same name. This compound is a dark purple solid under anhydrous conditions, bright orange when wet and which dissolves in water concomitant with hydrolysis.

APPLICATION
Chromium trioxide is mainly used in chrome plating. It is typically employed with additives that affect the plating process but do not react with the trioxide. The trioxide reacts with cadmium, zinc, and other metals to generate passivating chromate films that resist corrosion.
A Chromic Acid/ Phosphoric Acid solution is also the preferred stripping agent of anodic coatings of all types.
Besides it is also used in wood anticorrosion, medicine, catalyst, pigment and the production of other chromium products.
