Potassium dichromate

Potassium dichromate (CAS 7778-50-9), also known as bichromate of potash, is an inorganic chromium salt used industrially as a powerful oxidizing agent and corrosion inhibitor. It is a core reagent in surface treatment, tanning, and analytical chemistry.

In these sectors, controlled oxidation is required at scale to ensure consistent results. In leather processing, it serves as the primary oxidizing agent in chrome tanning, converting hides into durable, commercially finished leather products.

Textile dyeing operations use it as a mordant to fix dye onto natural fibers, improving wash and light fastness in finished fabric. Metal finishing and anti-corrosion treatments rely on it to passivate steel and aluminum surfaces.

These treatments are essential for extending service life in demanding environments. In mining and metallurgy, it functions as a flotation reagent and surface modifier during complex ore separation processes.

Potassium dichromate is supplied as orange-red crystalline granules or powder. Technical grade is the standard commercial form, with laboratory-grade material available for analytical and quality control applications.

These high-purity options meet defined thresholds for sensitive industrial use. Packaging typically ranges from small drums to bulk quantities depending on specific industrial volume requirements and logistics.
