Mn3O4 manganese tetraoxide.
Mn3O4: Molecular formula: Mn3O4 Molecular weight: 228.82 Brownish black in powder. Density 4.856. Melting point 1705¡æ. Nature: It is not dissolved in the water, but partially dissolved in sulphric and hydrochloric acid. It's also the important raw material of electronics industry in the production of manganese zinc ferrites of magnetically soft materials. Mn3O4, after the ferric oxide(Fe2O3) and zinc oxide, certainly allocated in a mixture of proportion together with the pattern in making agglutination formation, can make soft magnetism ferrites of high performance to lead magnetism material. The magnetism material should have the narrow remanence curve with the magnetic pulsing. And its direct-current electronic resistivity is very high, as may avoid the eddy current loss. Therefore,it is available to manufacture in high quality inductor,including television fly-back transformer, telephone with transformer, magnetic materials, such as magnetic core, magnetic disks, magnetic tapes and magnetic read in canned data of computers. Our output is of 20000tons/per year. packing in 500kg woven bags.our factory is of ISO quality.
