Zinc sulfate heptahydrate, also known as zinc alum, is an inorganic compound with the molecular formula ZnSO4·7H2O. It is a colorless orthorhombic prismatic crystal that appears as a white crystalline powder. Highly soluble in water and slightly soluble in ethanol, this versatile compound is essential for industrial and agricultural applications.
When heated, zinc sulfate begins to decompose at 200°C, fully decomposing at 770°C. This compound finds widespread use in various industries, including as media colorants, wood preservatives, and in the production of zinc salts. Furthermore, it is indispensable in medicine, man-made fibers, electrolysis, electroplating, pesticides, and as a bleaching agent in paper manufacturing.
However, zinc sulfate requires careful handling. It is harmful if ingested, can cause severe eye damage, and poses high toxicity to aquatic life. Strict precautions must be taken to prevent its release into the environment to avoid long-term detrimental effects on water ecosystems.
Shanghai Titop Chemicals Co., Ltd. offers premium-grade zinc sulfate heptahydrate, ideal as a supplementary fertilizer in agriculture. This product provides the essential trace element zinc, crucial for optimal plant growth and development.
