Ferrite block

2020-07-29

The ferrite cube is also called iron oxide. It is made of ferric oxide and one or more other metal oxides (for example: nickel oxide, zinc oxide, manganese oxide, magnesium oxide, barium oxide, strontium oxide, etc.) Sintered. Its relative permeability can be as high as several thousand, the resistivity is 1011 times that of metal, and the eddy current loss is small. It is suitable for making high-frequency electromagnetic devices. The ferrite block is iron and one or more other suitable ones. Composite oxides of metal elements. The properties are semiconductors and are usually used as magnetic media. The most important difference between ferrite magnetic materials and metal or alloy magnetic materials is conductivity. Usually the former has a resistivity of 102 to 108Ω·cm, The latter is only 10-6~10-4Ω·cm.

The magnetic properties of ferrite cubes are also manifested in high magnetic permeability at high frequencies. Therefore, ferrite has become a non-metallic magnetic material that is widely used in the field of high frequency and weak electricity. Because of the magnetic energy stored in the unit volume of ferrite It is lower, and the saturation magnetization is also lower (usually only 1/3 to 1/5 of pure iron), which limits its application in low-frequency high-power and high-power fields that require higher magnetic energy density
