Manganese carbonate

Manganese carbonate (CAS 598-62-9), also sold as manganous carbonate, is an inorganic manganese salt used across food, feed, pharmaceutical, and industrial markets as a manganese source and pH buffer. It functions as a precursor to other manganese compounds and as a catalyst component in chemical manufacturing. In animal feed and agricultural premixes, it delivers manganese as a trace mineral supplement.

This supplement helps to meet nutritional specifications for livestock and poultry. Pharmaceutical and nutraceutical manufacturers use it as a mineral source in tablet and capsule formulations where controlled manganese content is required. In ceramics and pigment production, it acts as a colorant and flux precursor, contributing to specific fired-color outcomes. Industrial catalyst producers use it as a starting material for manganese oxide catalysts.

These catalysts are applied in oxidation and decomposition reactions. Manganese carbonate is supplied as a pink to light-brown powder in technical and feed-grade specifications for various industrial uses. Food-grade and pharmaceutical-grade material is available to FCC and USP standards for regulated applications. This ensures the highest level of safety and compliance for sensitive manufacturing processes.

Standard packaging ranges from multi-wall bags to bulk quantities, with typical purity levels from 43–46% Mn content depending on grade. This versatility makes it a staple in global chemical distribution.
