Zinc Sulphate Heptahydrate
Zinc Sulphate Heptahydrate
It is an inorganic compound with the molecular formula ZnSO4 · 7H2O, commonly known as alum or zinc alum. Colorless rhombic prismatic junction
Crystal, white crystalline powder, soluble in water, slightly soluble in ethanol.
Used for artificial fiber coagulants. In the printing and dyeing industry, it is used as a mordant and an alkali resistant agent for dyeing with blue salt. It's making inorganic pigments
(such as lithopone), other zinc salts (such as zinc stearate, basic zinc carbonate), and the main raw materials for zinc containing catalysts. Used as wood and leather
Leather preservation agent, bone glue clarification and preservation agent. It can also be used to prevent diseases in fruit tree nurseries and to manufacture cables and zinc fertilizers.
