  • Process for the production of manganese dioxide
    Patent number: 4590059
    Abstract: Manganese dioxide is produced from manganous salts by mixing a manganous salt with an alkali metal permanganate and/or ammonium permanganate followed by heating such mixture to about 150.degree. C. under an oxygen-containing atmosphere until at least 85% of the manganous salt is converted to manganese dioxide and then further elevating the temperature to about 250.degree. C. and maintaining this temperature until the surface area of the manganese dioxide is between about 3 square meters per gram and about 12 square meters per gram.
