| Zinc chloride is in the form of white hexagonal crystal particles or powder. It is one of the important commodities in the inorganic salt industry and has a wide range of applications, many of which are used in printing and dyeing factories and the production of dyes. Zinc chloride is easily soluble in water, soluble in methanol, ethanol, glycerol, ether, acetone, and insoluble in liquid chlorine. It has strong deliquescence and can absorb moisture from the air and deliquescent, with the characteristic of dissolving metal oxides and cellulose. Molten zinc chloride has excellent conductivity. | |||||||||
