Why Choose Our Chromium(III) Nitrate Nonahydrate?

1. Precision Engineered for Critical Applications

From hydrogenation catalyst carriers to eco-friendly trivalent chromium plating, our Chromium(III) nitrate nonahydrate ensures:

• Catalyst Manufacturing: Low sulfur/alkali metals (<50ppm) prevent poisoning in methanol synthesis.
• Metal Surface Treatment: Replaces toxic hexavalent chromium (Cr⁶⁺) with ≤10ppm heavy metals.
• Pharmaceuticals: USP/EP-grade crystals with controlled Cl⁻/SO₄²⁻ (<50ppm) for API synthesis.

2. Tailored Solutions, No Compromise

• Customization: Adjust crystal size (D50 10–50µm), solubility (>800g/L), or Fe/Na levels.
• Eco-Friendly Production: Closed-loop systems recycle 98% wastewater into sodium nitrate byproducts.

3. Risk-Free Procurement

• Free Samples: 500g trial batches with full COA.
• MOQ 25kg: Ideal for R&D validation or small-scale production.

Key Industrial Uses of Chromium(III) Nitrate Nonahydrate

1. Catalyst Manufacturing

Enhance activity in copper-chromium catalysts for methanol conversion. Our liquid form eliminates 15–20% dissolution costs versus competitors’ solid products.

2. Trivalent Chromium Plating

Achieve ≥800 HV coating hardness without Cr⁶⁺ toxicity. Pre-mixed bath solutions simplify compliance with EU ELV/REACH standards.

3. Water Treatment

Corrosion-inhibiting additives compatible with polyacrylamide flocculants. pH-neutral variants available for NSF/ANSI 60-certified systems.

4. Specialty Ceramics & Pigments

Ultra-low transition metals (Cu/Ni ≤5ppm) ensure color stability in high-temperature glazes.

Technical & Supply Chain Assurance

Rigorous Quality Control

• Batch Traceability: Every shipment includes ICP-MS impurity profiles.
• Stability: 24-month shelf life in sealed containers.

Global Logistics

• Hazardous Goods Certified: Safe air/sea transport via DHL, FedEx, or COSCO.
• Inventory Reserves: Priority access for contracted clients.

FAQs

Q: Can you match Sigma-Aldrich's purity for pharmaceutical use?
