Chromic Anhydride is an inorganic substance with a molecular formula of CrO3 and a molecular weight 99.99. It is dark red or dark purple orthorhombic crystal, easy to deliquescence. It begins to decompose when heated to the melting point and decomposes completely when heated to the boiling point.

Chromic Acid uses:

Chromic Anhydride is a compound for producing chromium, and it is also an oxidizing agent and a catalyst. They are also used for wood preservation, electroplating, etc., and are prepared by the concentrated sulfuric acid and potassium dichromate reaction.

Chromium Trioxide is the primary raw material for electroplating chromium. In chromium electroplating production, chromic anhydride’s content varies greatly, between 50 and 500g/L. A bright coating can be obtained only by controlling the appropriate temperature and current density. Its solution can also contribute to a passivation film on zinc coating to improve its defensive performance.

Chromic Anhydride is the most essential raw material in the electroplating industry. The electroplating industry will use Chromic Anhydride. Raw materials for chrome plating such as bicycles, sewing machines, watches, instruments, flashlights, and daily hardware.
