Brief Overview

Zinc Chloride, also known as Zinc Dichloride, is a white coloured crystalline inorganic solid compound. It exists in nine crystalline forms, all of which are hygroscopic, water soluble, and deliquescent. It does occur naturally as a mineral form, but this mineral is very rare occurring and does not carry the same chemical formula as pure Zinc Chloride. This mineral is called Simonkolleite and its chemical formula is Zn5(OH)8Cl2H2O. Zinc Chloride is most commonly utilized in textile processing and metallurgical flux production.


Manufacturing Processes

Zinc Chloride in its anhydrous form is manufactured by the combination of Zinc metal and Hydrochloric Acid. The byproduct resulting from this reaction is Hydrogen gas. The hydrous form of Zinc Chloride is manufactured by the combination of Zinc Sulfide and Hydrochloric Acid. As a product, Hydrous Zinc Chloride consists of many impurities and water, which can be furthermore removed by the recrystallisation of hot Dioxane. Anhydrous Zinc Chloride, however, can be furthermore purified by passing it through a stream of Hydrogen Chloride gas by a sublimation reaction, after which this is heated in the presence of dry Nitrogen gas at 400 degrees Celsius. Due to its property of hygroscopicity and its good electrical conductivity, it serves as a critical component for maintaining water purity as well as a good electrical compound.

Water Treatment Industry

Zinc Chloride is utilized for purifying water due to its hygroscopicity. It also has the ability to reduce the corrosion rate of metals which is why it is often utilized as an inner wall coating in cooling towers.


Agricultural Industry

Zinc is one of the major constituents which contribute towards the growth of plants, thus it is utilized with chelating agents in solution form which is then sprayed to the plants. This solution is utilized in zinc scarce farming areas.


Metallurgy Industry

Zinc Chloride is normally utilized as a flux for cleaning metal surfaces before they are soldered/welded.


Battery Industry

Zinc Chloride paste is used in batteries for conducting electricity, increasing the electric power in batteries, and for absorbing moisture to prevent corrosion.
