Properties

Zinc sulfate heptahydrate is a white particle or powder with orthorhombic crystal. It is a common astringent. It will be weathered in dry air. When heated to 30 ℃, it loses one molecule of crystal water, six molecules of crystal water at 100 ℃, seven molecules of crystal water at 280 ℃, and decomposes into zinc oxide and sulfur trioxide at 767 ℃. It is soluble in water and slightly soluble in ethanol and glycerol. It is mainly used as raw materials for manufacturing zinc barium and other zinc salts, as well as important auxiliary raw materials for viscose fiber and vinylon fiber. It is also used as printing and dyeing mordant, wood and leather preservation agent, bone glue clarification and preservation agent, medical emetic and fungicide, and trace element fertilizer in agriculture.
