1.Properties: Electrolytic manganese dioxide is black crystal or brown black powder. It is used as catalyst and insoluble in water and nitric acid.
2.Specifications (It can be produced by per customer’s requirement):
3.Application:Electrolytic manganese dioxide is mainly used for dry battery depolarizer.
(1) Alkaline manganese is suitable for alkaline zinc-manganese dioxide cell.
(2) The mercury-free alkaline manganese is suitable for alkaline zinc-manganese battery。
(3) Raw materials of lithium manganese battery.
In electronics industry, it is used as raw materials of Mn-Zn ferrite magnetic materials. In steel industry, it also can be used as ferro-manganese alloy materials and auxiliaries for increasing industrial thermal energy. In gas masks, it is used to absorb carbon monoxide. In chemical industry, it is used as oxidizing agent such as synthesis of purpurin, catalyst for organic synthesis, painting and oil drying agent, ceramic, enamel salt and manganese glaze raw materials and also used in fireworks, removing iron to purify water, medicine, fertilizer and fabric dyeing and printing etc.
