Product Overview

• Sodium Dichromate is an inorganic hexavalent chromium compound widely used as a strong oxidizing agent across leather tanning, metal treatment, and specialty chemical manufacturing industries. It appears as bright orange to red crystalline solid, highly soluble in water, and is commercially supplied in both anhydrous and dihydrate crystalline forms. Procorbay International supplies industrial-grade Sodium Dichromate serving as a key raw material in chromium chemical manufacturing, leather tanning agent production, and metal surface treatment applications, with strict attention to regulatory handling requirements given its hexavalent chromium classification.
• Sodium Dichromate is manufactured through the processing of chromite ore via alkaline roasting and subsequent acidification and crystallization steps, followed by drying to achieve the required anhydrous or dihydrate crystalline form. Procorbay sources Sodium Dichromate from established chromium chemical manufacturers with consistent quality control over purity, moisture content, and impurity-profile specifications.
• Industrially, Sodium Dichromate serves as the foundational raw material for the production of chromic acid, various chromium oxide pigments, and basic chromium sulfate used in leather tanning (chrome tanning) processes, where its oxidizing properties are essential for stabilizing collagen fibers in hide processing. It also functions as a strong oxidizing agent in various metal surface treatment and passivation processes, including chromate conversion coatings used for corrosion protection, and serves as a raw material in the synthesis of various chromium-based catalysts and specialty chemical compounds. Given the well-documented health and environmental hazards associated with hexavalent chromium compounds, Sodium Dichromate is subject to strict regulatory controls in most jurisdictions, and Procorbay advises buyers to ensure full regulatory compliance and appropriate occupational safety measures throughout handling and downstream use.
• Given its foundational, though tightly regulated, role in chromium chemical and leather tanning supply chains, Procorbay maintains dependable sourcing of Sodium Dichromate for buyers with appropriate regulatory authorization and handling infrastructure.
