Chromic acid supplied by Zhangencong has a minimum assay of 99.8% CrO3, with water-insoluble matter at 0.02% max, sulfate at 0.06% max, sodium at 0.05% max, chloride at 0.005% max, and iron limited to 0.005% max. The inclusion of iron specification suggests tighter control over metal impurities compared to similar listings. This product is produced in Jiayuguan, Gansu, using refined crystallization techniques.
Typical commercial chromic acid does not always include iron testing, making this specification a differentiator. The presence of iron below 0.005% indicates potential use in high-precision applications such as aerospace plating or analytical reagents. The material is likely handled in sealed containers to prevent oxidation and moisture absorption, consistent with standard industrial practices for anhydrous CrO3.
This grade is suited for electroplating, glass coloring, and oxidation catalysis in chemical synthesis. Buyers include manufacturers of decorative and hard chrome finishes, specialty glass producers, and research labs requiring low-metal contaminants. Packaging is provided in hermetic steel drums of 25kg, 50kg, 100kg, 200kg, or 250kg net weight. Trade terms such as MOQ, Incoterms, and lead time are not disclosed and must be confirmed directly with the supplier.

Before ordering chromic acid from Zhangencong, verify the iron content per batch using ICP-MS or AAS, confirm the drum liner material is polyethylene, and request a certificate of analysis for CrO3 assay, sulfate, chloride, and insolubles. Ensure the supplier can provide a GHS-compliant safety data sheet and batch traceability. Do not accept material without documented test results.
