Description

Zinc Sulphate is an essential inorganic salt widely recognized for its role as a critical source of zinc, a vital micronutrient. Its high solubility and bioavailability make it a cornerstone ingredient in numerous industrial and agricultural processes. This compound is indispensable for manufacturers in the animal feed, agriculture, and chemical synthesis sectors seeking a reliable and consistent source of zinc ions.

Application

• Animal Nutrition: A primary zinc source in premixes and mineral feeds for livestock, poultry, and aquaculture to prevent deficiencies and support growth, immune function, and reproduction.
• Agricultural Fertilizers & Foliar Sprays: Used as a micronutrient fertilizer to correct zinc deficiencies in crops, improving yield, quality, and plant resilience.
• Dietary Supplements & Food Fortification: Employed in the manufacture of human nutritional supplements and for fortifying food products like cereals and flour.
• Chemical Manufacturing: Serves as a raw material or catalyst in the production of other zinc compounds, pigments, and dyes.
• Water Treatment: Acts as a coagulant aid and for controlling hydrogen sulfide odor in wastewater treatment processes.
• Electroplating & Galvanizing: Used in electrolyte formulations for zinc electroplating to provide corrosion-resistant coatings on metal parts.
• Pharmaceuticals: Utilized as an active pharmaceutical ingredient (API) in topical antiseptics and astringents.
