Chromic Acid is most known for its use in the metal finishing (intermediate in chromium plating) industry. Other common uses are as a wood preservative, production of plastic products, ceramic glazes and to clean laboratory glassware. Chromic Acid is also used in Magnetic Tapes, as a Catalyst, in copper stripping, aluminum anodizing, as a corrosion inhibitor, in photography, as a purifying oil and acetylene , also as a oxidizer in organic synthesis.
