Zinc sulfate (CAS 7446-19-7) (also spelled zinc sulphate) is a very water soluble, clear, crystalline compound prepared by heating zinc sulphide ore in air and dissolving out and recrystallizing the sulphate. It is commonly used as the heptahydrate form; it occurs naturally as the mineral goslarite, and can be prepared by reacting zinc with sulfuric acid. The crystalline sulfate is known commonly as white vitriol.
It loses water at 30°C to give the hexahydrate and more water is lost at 70°C to form the monohydrate. The anhydrous salt forms at 280°C and this decomposes above 500°C. It is used in agriculture as a weed killer and to give protection against pests; It is used to supply zinc in animal feeds and fertilizers; It is also an important constituent of the precipitating bath in the manufacture of viscose rayon and in electrolyte for zinc plating; It functions as a mordant in dyeing; as a preservative for skins and leather; and as an astringent and emitic in medicine.

Application of Zinc Sulfate
Zinc is one of the essential elements for plant and animal life. Zinc deficiency in animals was not recognized until 1934. Today’s sophisticated farmer understands the importance of zinc in maintaining normal health and increased yields, especially in swine and poultry. In swine, a lack of zinc in the diet causes parakeratosis, characterized by dermatitis, diarrhea, vomiting, decreased appetite, severe weight loss and eventual death. In poultry, zinc deficiency results in loss of appetite, growth retardation, blood disorders, arthritic deformities, bone diseases and death. Zinc supplements to the diet often cause prompt recovery. Zinc Sulfate is the optimum source of zinc in animal feeds as the nutritional source of zinc due to its biological availability.In plants zinc serves as a growth hormone and influences protein synthesis. Zinc deficiency often causes stunting of the plant, yellowing of the leaves, and decreased yields of seed, grain, vegetables or fruit. In the United States zinc deficient soils are found in 32 states. At least 41 crops are reported to be affected by zinc deficiency. Spray applications of a four to six percent solution may be employed on trees during the dormant period. Zinc Sulfate is often used on crops such as pecan, deciduous fruits, peanuts, cotton, corn, vegetables and especially citrus. Since zinc is required in such small amounts it is classified as a trace element or micronutrient.
Zinc Sulfate is used in the manufacture of viscose rayon fiber. It is one of the ingredients In the spinning bath where it promotes coagulation and crenellation of the fiber. Zinc Sulfate Solution is the ideal source of zinc in the production of Zinc Stearate. It is used as a catalyst in numerous chemical operations. In water treatment, Zinc Sulfate finds application as a corrosion inhibitor in cooling towers and municipal water systems. Zinc Sulfate also finds use in production of pigments, preservation and clarification of glue, in flame proofing compounds, as a mining flotation agent, in wood preservatives, in electro metallurgy and electro galvanizing.
Zinc Sulfate can also be used in many diverse industrial applications and may be used in place of zinc oxide. Please contact us if you have a specific application or requirement.
