Zinc sulphate Heptahydrate
CAS: 7446-20-0
Origin: China

Zinc sulfate heptahydrate, with the chemical formula ZnSO4 · 7H2O, is an important inorganic salt compound that usually exists in the form of white crystals or powders.
It plays a key role in multiple industrial and agricultural applications, and has attracted much attention due to its unique chemical properties and wide range of uses.
From a chemical structure perspective, heptahydrate zinc sulfate is a hydrate of zinc sulfate containing seven crystalline water molecules. This structure makes it relatively stable at room temperature, but gradually loses its crystalline water when heated, ultimately transforming into anhydrous zinc sulfate. This property is of great significance in industrial production because by controlling the heating conditions, the moisture content of the product can be precisely adjusted to meet the needs of different applications.
In the field of agriculture, heptahydrate zinc sulfate is an important trace element fertilizer. Zinc is one of the essential trace elements for plant growth, involved in the synthesis and activation of various enzymes in the plant body, and has important effects on plant growth and development, photosynthesis, and stress resistance. Seven water zinc sulfate, as a raw material for zinc fertilizer, is widely used in the cultivation of various crops, especially zinc sensitive crops such as corn, rice, wheat, etc. By applying heptahydrate zinc sulfate fertilizer, it can effectively supplement the zinc element in the soil, improve crop yield and quality.

In addition to agricultural applications, heptahydrate zinc sulfate also has a wide range of uses in the industrial field. It is a raw material for manufacturing other zinc salts, such as zinc oxide, zinc sulfide, etc. These zinc salts have important applications in industries such as rubber, coatings, plastics, ceramics, etc. In addition, heptahydrate zinc sulfate can also be used as an additive in electroplating solutions to improve the quality and corrosion resistance of the electroplating layer. In the field of medicine, zinc sulfate heptahydrate also has certain medicinal value and can be used to treat certain skin diseases and oral ulcers.
