Products Description of Trimanganese tetraoxide CAS#1317-35-7

Manganese tetraoxide is a black tetragonal crystal, also known as manganese pyroxene, black manganese ore, and active manganese oxide. It is calcined into crystals and belongs to the spinel class. It is an important industrial raw material.

Manganese tetraoxide is mainly used in the electronics industry and is a raw material for producing soft ferrites. Soft ferrites are made by sintering and molding manganese, zinc, and iron oxides in a certain ratio. They have a narrow remanent magnetic induction curve and can be repeatedly magnetized. At the same time, their DC resistivity is very high, which can avoid eddy current losses.

Product Application of Trimanganese tetraoxide CAS#1317-35-7

It is mainly used in the electronics industry and is the raw material for producing soft ferrites. Soft ferrites are made by mixing manganese, zinc and iron oxides in a certain ratio and then sintering them. They have a narrow remanent magnetic induction curve and can be repeatedly magnetized. At the same time, their DC resistivity is very high, which can avoid eddy current losses. They can be used as magnetic cores, disks and tapes for storing information in electronic computers, transformers and high-quality inductors for telephones, TV flyback transformers, magnetic heads for magnetic recording, inductors, magnetic amplifiers, saturated inductors, antenna rods, etc.

In addition, they can also be used as pigments for certain paints or coatings. Paints or coatings containing manganese tetraoxide sprayed on steel have better corrosion resistance than paints or coatings containing titanium dioxide or iron oxide.
