Used as a precursor in the production of ferrites for electronic components, manganese carbonate serves in manufacturing dry-cell batteries and acts as a pigment in ceramics and glass, providing pink to purple hues. It is also employed in animal feed and fertilizers as a manganese supplement to support metabolic functions and plant growth. In the chemical industry, it functions as a catalyst or reagent in synthesis processes. Additionally, it finds use in the preparation of other manganese compounds for industrial applications.
