Zinc Sulfate Monohydrate (ZnSO4·H2O) is a chemical compound distinguished by the presence of one water molecule per unit of zinc sulfate. This seemingly small difference from anhydrous zinc sulfate grants it distinct physical properties and a unique profile of applications, making it a preferred choice in many industrial, agricultural, and nutritional sectors.

Chemically, Zinc Sulfate Monohydrate is an ionic salt formed between zinc and sulfuric acid. Its appearance as a white crystalline powder is consistent across various purities. A key characteristic that sets the monohydrate form apart is its hygroscopic nature, meaning it readily absorbs moisture from the atmosphere. This property necessitates careful storage and handling to maintain its integrity and prevent clumping.

The manufacturing process for Zinc Sulfate Monohydrate typically involves reacting zinc oxide or zinc metal with sulfuric acid under controlled conditions, followed by crystallization. The subsequent drying process is optimized to yield the monohydrate form, ensuring a specific water content. Manufacturers in China, like us, focus on producing high-purity Zinc Sulfate Monohydrate to meet the stringent demands of various industries, including those requiring food and feed grades.

When considering purchasing Zinc Sulfate Monohydrate, understanding its specifications is crucial. Key parameters often include assay (purity of ZnSO4), zinc content, and limits for impurities such as lead, arsenic, and cadmium. The FCC (Food Chemical Codex) grade, for instance, adheres to strict standards for use in food and nutritional supplements. The consistency in particle size, often specified in mesh sizes, is also important for ease of handling and dissolution in specific applications.

The monohydrate form generally exhibits higher solubility in water compared to anhydrous forms, which is advantageous in applications requiring quick dissolution, such as in liquid fertilizers or certain chemical formulations. This enhanced solubility, coupled with its availability as a cost-effective white powder, makes it an attractive option for many users seeking a reliable zinc source.
