Chromic Acid

Chromic acid is a powerful oxidizing agent widely used in metal finishing, surface treatment, and industrial chemical applications. Known for its strong reactivity and ability to form durable protective coatings, it is a critical material in electroplating, anodizing, and passivation of metals, where it enhances corrosion resistance and surface hardness. Its effectiveness in cleaning laboratory glassware, etching, and polishing makes it a trusted compound in both research and industrial environments.

Beyond metal finishing, chromic acid functions as a reagent, catalyst, and intermediate in various chemical pathways. It is used in pigment and dye production, wood preservation, and specialty coatings, while also serving in limited applications in pharmaceutical synthesis and organic reactions due to its strong oxidizing properties. With its high performance in surface protection, durability, and precision processing, chromic acid remains an important chemical for industries requiring long-lasting finishes, reliability, and technical performance.
