Sintered Hard Ferrite Tile Magnets

The magnetic energy of ferrite tiles is mainly manifested in high permeability at high frequencies. Therefore, the ferrite core has become a non-metallic permanent magnet material that is widely used in the high-frequency weak current installation industry. Because the electromagnetic energy stored in the volume of the ferrite core is low, and the saturation magnetization is also low (generally only 1/3-1/5 of pure iron), it is limited in the specified higher electromagnetic energy relative to The density of the generation of weak electricity and the use of high-power industries The magnetic energy of ferrite magnetic tiles is mainly manifested in high magnetic permeability at high frequencies.

The production process of calcined ferrite magnetic tiles is mainly divided into wet-pressed heterosexual friends, dry-pressed gays, and dry-pressed heterosexuals. The difference between heterosexuals and gays depends on whether there is a trending electromagnetic field when the press is formed. The key details are here. Introduce the processing technology of wet pressing the opposite sex friend. The wet pressing production process is: raw material—pre-sintering—coarse crushing (primary ball mill)—seasoning—secondary ball mill (wet milling)—electromagnetic field forming—calcination—cutting— -Cleaning—Magnetization. Because the forming slurry contains water, the particles formed in the electromagnetic field are very easy to be converted into, so they can obtain a higher degree of orientation than dry-pressed friends of the opposite sex, and their characteristics are also higher.

Sintered Hard Ferrite Tile Magnets

General Introduction
Sintered Ferrite magnet (Ceramic Magnets, Hard Ferrite Magnet) were developed in the 1960’s as a low cost alternative to metallic magnets. Even though they exhibit low energy (compared with other permanent magnet materials) and are relatively brittle and hard, Sintered Ferrite magnet (ceramic magnets, Hard ferrite magnet) have won wide acceptance due to their good resistance to demagnetization, excellent corrosion resistance and low price per pound. In fact, measured by weight, ferrite represents more than 75 percent of the world magnet consumption. Sintered Ferrite Magnet (Hard Ferrite Magnet) is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors.

The elements of Sintered NdFeB Magnet (Hard Ferrite magnet) are ferric oxide/barium, strontium. Ferrite has higher coercive force and higher resistance to be demagnetized and oxidized than other non-rare earth permanent magnets. The biggest advantage of such magnet is their low cost. It is widely used from motors and loudspeakers to toys and craft, industrial holding magnet etc.

Besides industrial application, Sintered Ferrite magnet (Ceramic Magnets, Hard Ferrite Magnet) are widely use in Educational area.
