Zinc sulfate heptahydrate is an inorganic compound with the molecular formula ZnSO₄·7H₂O, commonly known as zinc sulfate or zinc sulfate. It occurs as colorless, orthorhombic prismatic crystals and a white crystalline powder. It is soluble in water and slightly soluble in ethanol. Zinc sulfate heptahydrate is used as a mordant, wood preservative, and bleaching agent in the paper industry. It is also used in medicine, synthetic fibers, electrolysis, electroplating, pesticides, and in the production of zinc salts.

PRODUCT USES

1. Supplements soil zinc to improve crop growth and stress tolerance.

Growth Promotion: Participates in auxin synthesis, enhances root activity and tillering ability.

Improves Stress Resistance: Enhances drought resistance and reduces the incidence of mosaic disease and vein spot.

Improves Quality: Promotes fruit enlargement, increases the vitamin content of fruits and vegetables, and improves the combustibility of tobacco.

2. Used as a mordant, wood preservative, and bleaching agent in the paper industry. It is also used in medicine, artificial fibers, electrolysis, electroplating, pesticides, and the production of zinc salts.

3. Zinc sulfate is a zinc supplement in feed. It is a component of many enzymes, proteins, and ribose in animals. It participates in carbohydrate and fat metabolism and catalyzes the conversion of pyruvate and lactate, promoting growth.

4. Used in artificial fiber coagulants. In the printing and dyeing industry, it is used as a mordant and an alkali-resistant agent for vanaramin blue salt dyeing. It is a major raw material for the manufacture of inorganic pigments (such as lithopone), other zinc salts (such as zinc stearate and basic zinc carbonate), and zinc-containing catalysts. It is used as a wood and leather preservative, and as a clarifier and preservative for bone glue. It is used as an emetic in the pharmaceutical industry. It is also used to prevent diseases in fruit tree nurseries, in cable manufacturing, and as a zinc micronutrient fertilizer.
