Trimanganese tetroxide is a black tetragonal crystal, also known as manganese, black manganese, and active manganese oxide. It is crystallized after firing. It belongs to the spinel class. The ion structure is in which divalent and trivalent manganese ions are distributed in two types Different lattice positions. Oxygen ions are cubic closely packed, divalent manganese ions occupy tetrahedral voids, and trivalent manganese ions occupy octahedral voids. When the temperature is below 1443K, trimanganese tetroxide has a deformed tetragonal spinel structure. The reason for the deformation is the ginger-Taylor effect. Above 1443K, it has a cubic spinel structure.

Application of manganese oxide powder:

1. Used in the electronic industry to produce soft ferrites, used as magnetic cores, disks and tapes for storing information in electronic computers, telephone transformers and commercial quality inductors, TV regression transformers, magnetic heads, inductors, magnetic amplifiers, saturation inductors Adapters, antenna rods, etc. It can also be used as a pigment in some paints or coatings.
2. Trimanganese tetroxide is a high-quality raw material for the synthesis of lithium manganese oxide, which is the cathode material of lithium ion batteries, and is also used in the manufacture of optical glass and the manufacture of low-temperature thermistors.
3. Used in the production of manganese, zinc, iron soft ferrite, magnetic cores, disks and tapes for storing information in electronic computers, telephone transformers and high-quality inductors, TV flyback transformers, magnetic recording heads, magnetic amplifiers, Saturated inductors, antenna rods, etc.
4. Trimanganese tetroxide is mainly used in the electronics industry as a raw material for the production of soft ferrite. The soft ferrite is made of manganese, zinc, and iron oxides mixed in a certain proportion and then sintered. It has a narrow remanence induction curve and can be repeatedly magnetized. At the same time, its DC resistivity is high, which can avoid eddy current loss. It can be used as magnetic cores, magnetic disks and tapes for storing information in electronic computers, telephone transformers and high-quality inductors, TV flyback transformers, magnetic recording heads, inductors, magnetic amplifiers, saturation inductors, antenna rods, etc. In addition, it can also be used as a colorant for certain paints or coatings. Paints or coatings containing trimanganese tetroxide sprayed on steel have better corrosion resistance than those containing titanium dioxide or iron oxide.

Storage conditions:
manganese tetroxide nanopowder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
