Used as a corrosion inhibitor in cooling water systems and industrial recirculating water to protect metal surfaces, especially in heat exchangers and pipelines. Acts as an oxidizing agent in chemical synthesis, particularly in the production of other chromium compounds. Employed in the dye and pigment industry for manufacturing colored pigments and in textile processing as a mordant for dye fixation. Applied in water treatment to form protective oxide layers on metal surfaces, preventing rust and scale formation. Also utilized in electroplating processes to improve coating adhesion and durability. Due to its strong oxidizing nature, handled with care in industrial settings.
