Barium permanganate
Barium permanganate is a chemical compound, with the formula Ba(MnO4)2.
Barium permanganate may be produced by disproportionation of barium manganate in a mildly acidic solution, or by oxidation of barium manganate with strong oxidants. Preparations relying on aqueous reactions of barium manganate are extremely slow process due to the low solubility of the manganate.
