The using field:

Properties: white or colorless, zinc sulfate heptahydrate is crystal or granule, and zinc sulfate monohydrate is a fluid powder or coarse powder. Odorless. The relative density of 1.957, the melting point of 100 ° C, soluble in water, the aqueous solution is acidic, slightly soluble in ethanol and glycerol. When the monohydrate is heated to 283 ° C, it loses water. Its heptahydrate is easily dehydrated and weathered in dry air at room temperature. When heated to 767 ° C, it decomposes into ZnO and SO 3 .

It is used in the production of beverages, dairy products, health products, zinc supplements, food additives and other products.

Zinc oxide food grade is a hexagonal close-packed (HCP) amphoteric oxide semiconductor known for such properties as high refractive index, excellent thermal conductivity, antibacterial effects, and anti-UV abilities. It is not easily soluble in water but soluble in acid and alkali. Zinc oxide powder appears white at room temperature and has a melting point of 1975℃ and density of 5.68g/cm3. After being treated in high temperature, due to the effusion of oxygen, zinc oxide powder shows light yellow. Zinc oxide food grade has a wide band gap (3.37eV), so it is suitable to be used in short-wavelength light-emitting materials, such as LED, LD, short-wavelength detectors, and optical filters. At room temperature, exciton binding energy of zinc oxide reaches 60meV, allowing it to outperform other wide-bandgap materials in luminous efficiency. Zinc oxide is therefore an important material of laser and has great potentials in optoelectronics.
