Chromic acid from Dingchen Industry(HK)Co., Limited is supplied as chromium trioxide (CrO3) in dark red flake form, with a minimum purity of 99.8% as confirmed by the supplier. The material is formulated as an aqueous solution of H2CrO4 and contains less than 0.01% sulfate content, which minimizes interference in precision oxidation reactions. This grade is engineered for industrial applications requiring consistent oxidizing power and low impurity profiles, particularly in metal finishing and pharmaceutical synthesis.
The product is manufactured under controlled conditions to maintain crystalline integrity and low moisture absorption. Typical industry standards for chromic acid allow for 99.0% to 99.9% CrO3 content; this listing exceeds the lower bound with its 99.8% specification. Packaging is in sealed HDPE-lined drums to prevent hygroscopic degradation and contamination during transit. The material is classified under UN 1484 for transport, requiring hazmat documentation and compliance with IMDG and IATA regulations.
Buyers in electroplating, aerospace component finishing, and specialty chemical synthesis use this material for its reproducible surface activation properties. End users include manufacturers of high-tolerance metal parts, reagent suppliers, and laboratories producing chromium-based intermediates. Trade terms are available as FOB Shanghai or CIF destination, with bulk packaging in 25kg or 50kg units. Minimum order quantities are not stated; buyers must confirm directly with the supplier.
