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.
