Description

What is Sintered Ferrite magnet?
Sintered Ferrite magnet (Ceramic Magnet), aslo name Ferrite Magnet, Ceramic Magnets, Hard Ferrite Magnet, are chemical compounds consisting of ceramic materials with iron(III) oxide (Fe2O3) as their principal component. Many of them are magnetic materials and they are used to make permanent magnets, ferrite cores for transformers, and in various other applications.

Ferrite Magnet are usually non-conductive ferrimagnetic ceramic compounds derived from iron oxides such as hematite (Fe2O3) or magnetite (Fe3O4) as well as oxides of other metals. Ferrites are, like most other ceramics, hard and brittle. In terms of their magnetic properties, the different ferrites are often classified as “soft” or “hard”, which refers to their low or high magnetic coercivity.

Sintered 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 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 is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors.

The elements of Sintered NdFeB 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 are widely use in Educational magnet area.
 
Sintered Ferrite magnet feature:
Sintered Ferrite (Sintered Ferrite) of the main raw material including BaFe12O19 and SrFe12O19, according to the orientation of magnetic crystal divided into isotropic and anisotropic magnets.Because of its low cost and moderate magnetic properties and become more widespread application of a magnet.Ferrite magnet is made of by ceramic method, texture is relatively hard, it is a brittle material, due to ferrite magnets have good temperature resistance and low cost has become more widespread application of permanent magnets.

The main raw materials include sintered ferrite BaFe12O19 and SrFe12O19, according to the orientation of the magnetic crystal divided into isotropic and anisotropic magnets. Because of its low price and moderate magnetic properties and become the most widely used of a magnet. Annual output of 300 tons or more. Ferrite magnet is made of by ceramic method, the texture is relatively hard, it is a brittle material, the ferrite magnets have good temperature resistance and low prices, has become the most widely used permanent magnets.
 
Sintered Ferrite magnet Application:
Sintered Ferrite magnetic partakers wet-sex square, circular magnetic, magnetic ring, magnetic cutting. Products are widely used in electrical, electronics, appliances, speakers, health supplies, toys, stationery, suction devices and other fields.
