Ethanedioicacid, ammonium iron(3+) salt (3:3:1), trihydrate (9CI) Oxalic acid, ammoniumiron(3+) salt (3:3:1), trihydrate (8CI) Ammonium iron oxalate,(NH4)3Fe(C2O4)3, trihydrate
High Purity for Superior Performance: Our product features a purity level of ≥ 99.0%, minimizing impurities that can negatively impact sensitive processes. This ensures exceptional results in applications like precision anodizing, where color uniformity is critical, and in analytical chemistry, where accuracy is paramount.
Excellent Batch-to-Batch Consistency: We enforce strict quality control to guarantee that every batch meets the same tight specifications. This consistency saves you time and resources by eliminating the need for process recalibration, ensuring stable and repeatable outcomes in your production line.
Optimized for Aluminum Anodizing: Specifically formulated for the surface finishing industry, our Ammonium Ferric Oxalate delivers vibrant, uniform, and lightfast colors on anodized aluminum, ranging from light gold to deep bronze and black. Its reliable performance ensures a flawless, high-value finish.
High Photosensitivity: Ideal for photographic and blueprinting (cyanotype) applications. Its high sensitivity to UV light allows for the creation of sharp, high-contrast, and detailed Prussian blue images with optimized exposure times.
Superior Solubility and Form: The uniform crystalline structure ensures excellent and rapid solubility in water. This makes it easy to prepare stable, clear solutions for your baths and formulas, while the defined particle size helps reduce dust and improve handling safety.
