High-Purity Chromium Sulfate Solution | Custom Solutions for Catalyst & Industrial Applications
What Is Chromium Sulfate Solution?
Chromium sulfate solution is a specialized chemical widely used in eco-friendly trivalent chromium plating, catalyst synthesis, and surface treatment. As a stable, water-soluble compound (CAS 10101-53-8), it offers superior performance over traditional hexavalent chromium, aligning with global environmental regulations like REACH and RoHS. At Yunli Chemical, our solutions are engineered for ultra-low impurities (Fe ≤30ppm), customizable pH (2.5–3.5), and seamless integration into automated production lines.
