Explanation
Also known as iron oxide, various types of compounds formed by the combination of elements and oxidation. There are different structure types, such as sodium chloride type, spinel type, magnetite type, garnet type, etc., which show different magnetic order, magnetocrystalline anisotropy and other magnetic properties as well as high-frequency characteristics. The preparation of ferrite mainly adopts powder metallurgy sintering process. Now it is widely used in many aspects, such as permanent magnet, high-frequency core, rectangular magnetic loop core materials, etc. Its characteristics are low price, simple processing technology, and wide application range.
