Key Applications
1. Industrial Catalysts
CAS 10026-22-9 is vital for methanol synthesis, hydrogenation, and specialty catalyst systems. Our ultra-low iron content (≤30ppm) minimizes side reactions, while pH-stable formulations ensure batch-to-batch consistency.
2. Metal Surface Treatment
Replace hexavalent chromium with eco-friendly trivalent alternatives. Our non-caking cobalt nitrate resists humidity, ideal for automotive and aerospace coatings.
3. Pharmaceuticals
Meet BP/USP standards with ≤50ppm impurities and ≤0.07% moisture. Used in APIs and diagnostic reagents.
4. Advanced Ceramics & Pigments
Enhance color stability and texture in ceramics and paints with our high-solubility cobalt nitrate.
