Powerful Hard Sintered Ferrite Magnet Tiles Ferrite Permanent Magnets

 

Product Description

 

Processing

 

Having obtained the ferrite, the cooled product is milled to particles smaller than 2 µm, sufficiently small that each particle consists of a single magnetic domain. Next the powder is pressed into a shape, dried, and re-sintered. The shaping may be performed in an external magnetic field, in order to achieve a preferred orientation of the particles (anisotropy).
 
Small and geometrically easy shapes may be produced with dry pressing. However, in such a process small particles may agglomerate and lead to poorer magnetic properties compared to the wet pressing process. Direct calcination and sintering without re-milling is possible as well but leads to poor magnetic properties.
 
Electromagnets are pre-sintered as well (pre-reaction), milled and pressed. However, the sintering takes place in a specific atmosphere, for instance one with an oxygen shortage. The chemical composition and especially the structure vary strongly between the precursor and the sintered product.
 
To allow efficient stacking of product in the furnace during sintering and prevent parts sticking together, many manufacturers separate ware using ceramic powder separator sheets. These sheets are available in various materials such as alumina, zirconia and magnesia. They are also available in fine, medium and coarse particle sizes. By matching the material and particle size to the ware being sintered, surface damage and contamination can be reduced while maximizing furnace loading.
 
 

Ferrite magnets are sintered permanent magnets composed of Barium or Strontium Ferrite. This class of

magnets, with good resistance to demagnetization and high working temperature, has the popular

advantage of low cost. There are anisotropic and isotropic Ferrite magnets.

Ferrite magnets Advantage:

 

1. Ferrite magnets are corrosion free – for long term performance they are superb; if looked after they are capable of exceeding most products      life cycles.Ferrite magnets can be used up to +250 degrees C.

2. Ferrite magnets are  low cost, particularly in high volume production runs.

3. Ferrite Magnets resist chemical attacks from many of the alkaline solutions, dilute acids, organic solvents, and some hydroxides. They are fine

      foruse in salt water conditions .
