Name | Zinc sulphate | Molar Mass | 161.45 |
Chinese name | 硫酸锌/七水硫酸锌/一水硫酸锌 | Density | 1.31g/mLat 20°C |
Synonyms | zinc sulfate | Melting Point | 100°C |
Molecular Formula | ZnSO4 | UN IDs | UN 3082 9/PG 3 |
CAS | 7733-02-0 | HS Code | 2833 29 20 |
Zinc sulphate, chemical formula ZnSO4, colourless or white crystals, granules or powder, no smell. Melting point is 100°C, astringent taste. Density 1.31g/mLat 20°C. Soluble in water, aqueous solution is acidic, slightly soluble in ethanol and glycerol. Pure zinc sulphate does not turn yellow when stored in air for a long time, but it loses water in dry air and becomes white powder. There are a variety of hydrates: in the range of 0-39 ° C and water phase equilibrium of stable hydrates for zinc sulfate heptahydrate, 39-60 ° C for zinc sulfate hexahydrate, 60-100 ° C for zinc sulfate monohydrate. When heated to 280℃ all kinds of hydrates completely lose the water of crystallisation, decompose into zinc oxide sulphate at 680℃, further decompose above 750℃, and finally decompose into zinc oxide and sulphur trioxide at about 930℃.
Uses
Beneficiation: Inhibition of zinc-containing minerals, the principle of which is to form a film of hydrophilic zinc-containing minerals on the surface of easy-to-float sphalerite, so as to achieve the purpose of inhibiting sphalerite.
Agriculture: Zinc sulphate is widely used as an agricultural fertiliser, providing plants with the zinc they need to grow and develop.
Batteries: Zinc sulphate is used as an electrolyte in some dry cell batteries such as zinc carbon and alkaline batteries.
Metal working: Zinc sulphate can be used as an electroplating solution for galvanising and protecting metal surfaces.
Packing specification
Packed in laminated plastic woven bag lined with plastic film bag, net weight per bag 25kg, 50kg, 1000kg.
