Zinc Sulfate (ZnSO₄) Details
Risso Zinc Sulfate (chemical formula ZnSO₄) is a high-purity inorganic compound produced under strict quality control to ensure consistency, solubility, and bioavailability. It is commonly supplied as zinc sulfate heptahydrate (ZnSO₄·7H₂O) or anhydrous zinc sulfate, appearing as a white crystalline or powdery solid.
Zinc sulfate is widely recognized as a vital zinc source in fertilizer formulations, animal feed additives, water treatment, and electroplating processes. Risso® ensures superior product purity, optimized solubility, and excellent flow characteristics for efficient downstream use.
