Ceramic Hard Ferrite Materials

Grades 5 and 8 ceramic materials are anisotropic and must therefore be magnetized in the manufactured dimension.

Ceramic hard ferrite materials.

They exhibit higher levels of magnetic force than do ceramic 1 materials. Ceramic 1 hard ferrite an isotropic dry pressed ferrite material which may be magnetized in any direction. Home material grades hard ferrite ceramic the chemical composition of ferrite magnets is sro 6 fe2o3 strontium hexaferrite. They are electrically nonconductive meaning that they are insulators and ferrimagnetic meaning they can easily be magnetized or attracted to a magnet.

Field magnets for reed switch actuators electron beam correction and. At this temperature they undergo a chemical conversion and the resulting material is ferrite. The raw materials used to produce ferrite magnets are strontium carbonate and iron oxide both of which are readily available and low in cost. Typical applications include latches axial magnetic couplings for water meters frictionless bearings for watt hour meters stepper motors magnetic sensors ie.

The primary raw material ferrite is made by using iron oxide and strontium carbonate. Ceramic magnets are manufactured using powder technology techniques. These materials are mixed together and then elevated in temperature to 1800 2000 degrees f. Ceramic ferrite magnet material was first formulated in the 1950s and then further developed in the 1960s as a less expensive alternative to other types of magnet materials.
