Batteries require an electrolyte paste in dry-cell batteries and zinc chloride is used to make this paste. Zinc-manganese batteries or zinc-carbon batteries as they are called, are very common and are suitable for daily use.
In petroleum drilling, zinc carbonate reacts with H2S to generate a stable insoluble ZnS compound. After adding the zinc based additive this product, the mud’s performance is not affected by pollutants and corrosive H2S. It also acts as a sulfide scavenger.
Metal Welding Industry
Zinc ammonium chloride is applied to eliminate the metallic oxide on the surface of welding points.
