English description（英文原文，共 1095 字符）
Product Name:Zinc sulfate
English Name:Zinc sulfate
CAS No.:7733-02-0
Aliases:White vitriol, Zinc vitriol, Goslarite
Molecular Formula:ZnSO4
Physical Properties:White or slightly yellow crystalline powder, readily soluble in water, slightly soluble in ethanol. Aqueous solution is weakly acidic. Anhydrous density 3.54 g/cm³, melting point approx. 600°C (decomposes). Loses water of crystallization above 280°C, further decomposes to zinc oxide and sulfur trioxide at high temperatures.
Uses:Zinc sulfate is an important zinc salt raw material, widely used in electrogalvanizing, battery manufacturing, and zinc salt synthesis. In agriculture, it is used as a micronutrient fertilizer to prevent and correct zinc deficiency in crops. In pharmaceutical and daily chemical fields, it serves as an astringent and preservative. It is also used in dyeing mordants, wood preservation, and paper bleaching.
Technical Specifications:
Zinc sulfate content (as ZnSO4) ≥98.0%
Zinc (Zn) content ≥22.0%
Water insoluble matter ≤0.05%
Heavy metals (as Pb) ≤0.001%
pH of 5% aqueous solution: 4.0~6.0
