Ferrite magnet is an indispensable part of many machinery and equipment in life. Its existence value is very great. Here I can introduce you some related knowledge points, mainly from the main raw materials and the scale of use. To give you analysis. Interested customers can follow the editor to watch it!
Introduction to the main raw materials and use scale of ferrite magnets
The main raw materials of ferrite magnets include BaFe12O19 and SrFe12O19. It is made by the magnetic steel method of ceramic process. It has a relatively hard texture and is a brittle material. Because ferrite magnets have good temperature resistance, low price and moderate functions, they have become widely used permanent magnets. Classification of magnetic materials
Ferrite is a metal oxide with ferromagnetism. In terms of electrical characteristics, the resistivity of ferrite is much larger than that of metal and alloy magnetic materials, and it also has a higher dielectric function. The magnetic function of ferrite also shows that high-frequency magnets have higher magnetic permeability. Therefore, ferrite has become a widely used non-metallic magnetic material in the field of high frequency and weak current.
Ferrite is a sintered magnetic metal oxide composed of various iron oxide mixtures. The raw materials are mainly iron oxide, barium carbonate or strontium carbonate.
Because the magnetic energy stored in the unit volume of ferrite is low, the saturation magnetization is also low (usually as long as 1/3 to 1/5 of pure iron), which restricts it from requesting higher magnetic energy density of low frequency and strong electricity and The use of high power range.
