Ferrite Disc Magnets

The flat circular hard magnets made out through molding and sintering with raw
material of SrO or BaO and Fe2O3 called sintered ferrite (ceramic) disc magnet,
its surface is in black color. The round shape is one of the most common shapes
of ferrite magnets, which has a narrow range of magnetic energy product. The
magnetic energy product of different grades sintered ferrite disc magnets vary
from 1.1MGOe to 40 MGOe. Permanent ferrite (ceramic) disc magnets are applied
in household appliances, magnetic separation, crafts and so on.

Characteristics Of ceramic disc magnets
Ferrite(ceramic) discs are not corroded easily, because the main raw material
is oxide, so surface coating treatment is no longer needed.

Ferrite(ceramic) magnet discs are produced by powder metallurgy method, they
have low remanence, recovery of magnetic permeability is small, compared with
other permanent magnet discs, round ferrite disc magnets are hard and brittle,
have high coercivity, not easy to demagnetization, and low price, is the
cheapest round type permanent magnet.

Property&Grade Of Ferrite Disc Magnets
ceramic disk magnets are divided into anisotropy (allotropy) and isotropy
(isotropy). The magnetic properties of isotropic sintered ferrite disc magnet
have weak strength, but they can be magnetized in different directions of
magnets. The common properties of isotropic disc ferrite magnets are Y8T and
Y10T. The anisotropic sintered ferrite disc magnets have strong magnetic
properties, but they can only be magnetized along the predetermined magnetizing
direction of the magnet. Common grades of the anisotropic disc ferrite magnets
are Y25, Y30, Y35, Y30BH.
