One of the main purposes of the present manganese tetroxide EMM is to produce electronic grade. Manganese tetroxide ferrite is an important component of the soft magnetic material. Consistently the most modern in the world because of the rapid development in the electronics industry to improve product quality requirements for the production of electronic products, so the quality raw materials to create more high requirements. MN-Zn ferrite soft magnetic materials is the main raw material electronics products industry, its quality often determines the performance of electronic products.

Manganese tetroxide some quality soft magnetic materials, the quality of a wide range of manganese oxides that affect the boron powder performance of EMM depends on quality. Manganese tetroxide China's current production of electrolytic manganese metal powder production process, the oxidation of aqueous solution of the system in the use of hazardous materials are not allowed to remove impurities, and some part of it is difficult to get rid of some. Individual hazardous elements - silicon manganese tetroxide is increased in the production process. Soft magnetic materials, manufacturers of silicon manganese tetroxide has strict requirements for the content. The company's products currently in the production of selenium, manganese, silicon containing 100 ~ 150μg / g, 200 μg / g in the SiO2 content mainly. Several companies currently under 25μg / G manganese high purity silicon manganese tetroxide product can meet the requirements of the production can produce.

With the development of the ARC slag contains ingredients with a spatula and a small addition to the more familiar small spatula electrode 10% 20% ferromanganese or manganese metal powder made of the 0 ~ 0.5mm. Of manganese in welding functions: In addition to the metal-oxygen manganese powder agents, additives oxygen, sulfur and alloy used to absorb all the gas to absorb the liquid metal to prevent welding. Easy to use and the conditions under which air and water are not being oxidized, low strength for carbon and oxygen-containing manganese powder, and strict requirements for exposure. Manganese powder passivation treatment, after treatment, the oxygen in the range from 0.5% to 0.4% manganese content of the powder, and re-ventilation difficult. From manganese metal powder Paesibeyisyeonneun squeezed into electrolytic manganese metal powder and then piece the passivation process is simple. Currently, 2,000 t / and global demand for paesibeyisyeoneseo manganese, South Africa and China's major producing countries.

At the same time in both analysis and response to hydrogen evolution of manganese in the manganese sulphate solution from the cathode, electrolytic manganese metal deposition in the work itself, but the hydrogen evolution reaction and hydrogen evolution, the most of the measures taken to prevent the summer, especially in the production of electricity. It can not avoid altogether such temperature increases the hydrogen evolution metal powder supplier reaction is more severe. Thus, deposition electrolytic manganese metal cathode is always a certain amount of interaction or hydrogen being absorbed. From 0.015 to 0.020% hydrogen content in general. Some special cases, from 0.001 to 0.0006 percent hydrogen content of the requirements of the EMM. Not by dehydrogenation of EMM processing requirements are unachievable. Manganese and not hydrogen adsorption and entry of this compound produces only a piece of metal manganese heating under vacuum to 550 ~ 650 ℃ can take away most of the hydrogen.
