CHEMICAL DESCRIPTION:
Manganese Dioxide (MnO₂) is a manganese oxide found naturally as the mineral pyrolusite, appearing as a brownish-black powder. In the ceramic industry, it is used in glazes and bodies for antiquing effects. It is used as a black colorant additive in refractory and brick production, as a feed additive in oxide form after calcination in the animal feed sector, and widely as an electrode material in alkaline and zinc-carbon batteries in the energy sector. Turkey has extensive reserves with low import dependency.
