高纯度水钠锰矿及其制备方法
摘要：
一种制造锰的氧化物的方法，包括：在第一水溶液中使锰盐和碱性试剂反应以形成氢氧化锰；从所述第一水溶液中分离出所述氢氧化锰；将所述氢氧化锰混入水性介质中以形成氢氧化锰悬浮液；将所述氢氧化锰悬浮液与碱金属氢氧化物混合以形成第二水溶液；和氧化所述第二水溶液中的所述氢氧化锰以形成锰的氧化物。该干燥的锰的氧化物包含水钠锰矿、至多20％的黑锰矿和至多10％的六方水锰矿，可以还包含至多400ppm的阴离子，可以具有至少25m2/g的比表面积，并且可以具有大于3.5的平均氧化态。
摘要（英）：

A method of producing an oxide of manganese including reacting, in a first aqueous solution, a manganese salt and an alkali agent to form manganese hydroxide; separating the manganese hydroxide from the first solution; mixing the manganese hydroxide into an aqueous medium to form a manganese hydroxide suspension; mixing the manganese hydroxide suspension with alkali metal hydroxide to form a second aqueous solution; and oxidizing the manganese hydroxide in the second aqueous solution to form an oxide of manganese. The dried oxide of manganese includes birnessite, a maximum of 20% hausmannite,and a maximum of 10% feitknechtite, may further include a maximum of 400 ppm of anions, may have a specific surface area of at least 25 m<2>/g, and may have an average oxidation state of greater than3.5.
