Product Description

Zinc sulfate is the inorganic compound with the formula ZnSO4 as well as any of three hydrates. It was historically known as “white vitriol”. It is a colorless solid that is a common source of soluble zinc ions.Production methods:Synthesis with sulfuric acid and zinc oxide reaction after filtering, add dust replacement to remove impurities, after filtering, adding potassium permanganate oxidation, then through dry, separation, concentration, filtration, secondary displacement, pressure filtration, screening, made of zinc sulfate monohydrate. its


It is mainly used as raw material for making barium and other zinc salts, and is also an important auxiliary raw material for viscose fiber and vinylon fiber. Agriculture is used as trace element fertilizer, it is also used for plating, flotation, preventing fruit seedling disease and circulating cooling water treatment.

IUPAC name

Zinc sulfate

Other names

White vitriol / Goslarite

CAS number





The hydrates, especially the heptahydrate, are the primary forms used commercially. The main application is as a coagulant in the production of rayon. It is also a precursor to the pigment lithopone. Zinc sulfate is used to supply zinc in animal feeds, fertilizers, and agricultural spraysZinc sulfate, like many zinc compounds, can be used to control moss growth on roofs. It is used as in electrolytes for zinc plating, as a mordant in dyeing, as a preservative for skins and leather and in medicine as an astringent and emetic.


As a mineral ZnSO4·7H2O is known as goslarite. Zinc sulfate occurs as several other minor minerals Zinc-melanterite (Zn,Cu,Fe)SO4·7H2O (structurally different from goslarite). Lower hydrates of zinc sulfate are rarely found in nature: (Zn,Fe)SO4·6H2O (bianchite), (Zn,Mg)SO4·4H2O (boyleite), and (Zn,Mn)SO4·H2O (gunningite).
