Zinc carbonate (ZnCO3) is an inorganic ceramic compound that occurs naturally as the mineral smithsonite and is also produced synthetically for industrial applications. It serves primarily as a precursor material and pigment in coatings, rubber compounding, and pharmaceutical formulations, where its chemical reactivity and whiteness are valued. Engineers select ZnCO3 when zinc oxide sources with controlled decomposition profiles are needed, or in applications requiring non-toxic white fillers and corrosion inhibitors.
