Description
Zinc Sulfate Product Overview
Zinc sulfate is a white crystalline or granular powder that dissolves freely in water. The monohydrate (ZnSO4·H2O) contains at least 35% zinc, whereas the heptahydrate (ZnSO4·7H2O) contains at least 21%; the monohydrate is more concentrated and easier to store.
In addition, feed producers use it as the most common zinc source in premixes, and fertilizer producers use it to correct zinc deficiency in soils and in foliar sprays. Similarly, viscose rayon producers add it to the spinning bath, and metal finishers use it in zinc electroplating. Pharmaceutical companies also use it in oral zinc tablets and solutions, for example in WHO-recommended zinc therapy alongside oral rehydration.
Furthermore, other zinc compounds in our range include Zinc oxide, Zinc gluconate and Zinc Chloride.
