The uses of manganese

 MnO2 is zinc - manganese battery anode, was reduction in the battery discharge. Preparation of battery MnO2 raw materials mainly has natural MnO2, chemical MnO2and electrolytic MnO2. Natural Mn02 due to lower purity, generally applies only to production paste type zinc manganese dry battery, and suitable for dry cell with NMD quantity in the nature has less and less, and because the technology progress and the improvement of people's living standard as well as environmental protection strengthened day by day, with NMD production paste type zinc - manganese battery would gradually reduce. And alkaline zinc - manganese battery is growing rapidly. Therefore, EMD in zinc manganese dry battery in a dosage will also continue to increase. Especially production mercury-free zinc - manganese battery with high purity EMD demand will increase faster.

The application of manganese in electronic industry, electronic industry is the fastest one department in the global economy development, drive the development of the global economy. Magnetic materials, especially soft magnetic material is the basic raw material of electronic industry. In soft magnetic materials, manganese zinc ferrite is the most important, because it has narrow remanence curve, can be repeated magnetization, with high permeability under the action of high frequency, high resistance rate, low loss characteristics and so on, at the same time, the price is low, source extensively, have replaced most of the nickel zinc ferrite, in soft magnetic material in up to more than 80%. With manganese zinc ferrite core made of various inductors, transformers, coils, choke, etc. It has been widely used in communications equipment, household appliances products, computer products, industrial automation equipment.

The application of manganese in building materials, the mainly use of manganese in building materials of is in the production of glass as fade, coloring and clarifying agent, etc. The raw materials for the production of glass almost contain drill, iron and other impurities, it will impact the color of the glass, add right amount people Mn02 can make glass into a colorless, add different amount of Mn02 and can make glass has a different color. Another purpose of manganese in building materials is coloring the ceramic and brick, tile surface, such as the brown, green, purple, black and luster bright colors. Western Europe countries’ buildings decoration materials glazed tile, tile surface coloring is mainly to adopt MnO2 for coloring material, color bright, durable not easy fade, very popular.

The application of manganese in agriculture, manganese is an indispensable trace elements for plant normal growth, involve in photosynthesis and nitrogen transformation, participate in many enzyme activities and rebox process, can promote the synthesis of chlorophyll and carbohydrate operation. When the soil lack of manganese seriously, crop appear withered and yellow, poor growth, yield decline. According to the Chinese academy of sciences institute of nanjing soil and jiangsu academy of agricultural sciences research indicates that, Chinese soil lack of manganese above one hundred million mu of land, if applied 1kg manganese fertilizer in one mu of land every year, chinese agriculture need manganese fertilizer reached more than 100000 t. Manganese sulfate and a manganese oxide are high-quality manganese fertilizer.

Except for fertilizer besides, manganese in agriculture and many other applications, such as for bactericide, feed additives, etc.

Manganese power in environmental management applications, manganese in environmental protection, mainly for the of the sewage and waste gas treatment. The natural drinking water often contain certain impurities, need purification, use manganese dioxide to treated water especially suitable for groundwater to get rid of iron.
