1. Product description:
Zinc sulfate is also known as halo alum and zinc alum. It is a colorless or white orthorhombic crystal or powder at room temperature. It has astringent properties and is easily soluble in water. The aqueous solution is acidic and slightly soluble in ethanol and glycerin. Pure zinc sulfate does not turn yellow when stored in the air for a long time, and loses water in dry air to become a white powder. There are many kinds of hydrates: zinc sulfate heptahydrate is a stable hydrate in the range of 0-39°C in equilibrium with water, zinc sulfate hexahydrate at 9-60°C in 3Chemicalbook, and zinc sulfate monohydrate at 60-100°C. When heated to 280°C, various hydrates completely lose crystal water, decompose into zinc oxysulfate at 680°C, further decompose above 750°C, and finally decompose into zinc oxide and sulfur trioxide at about 930°C. ZnSO4·7H2O and MSO4·7H2O (M=Mg, Fe, Mn, Co, Ni) form mixed crystals within a certain range.
Zinc sulfate is mainly used as a raw material for producing pigment lithopone, lithopone and other zinc compounds. It is also used as a nutrient when animals are zinc-deficient, feed additives for animal husbandry, zinc fertilizer (trace element fertilizer) for crops, and man-made fibers. The important materials of the electro Chemicalbook, the electrolyte used in the production of metal zinc, the mordant in the textile industry, medical emetics, astringents, fungicides, wood and leather preservatives, etc. It is obtained by the action of zinc or zinc oxide with sulfuric acid or by extraction and refining of sphalerite after baking in a reverberatory furnace.
