Ceramic Hard Ferrite Materials

The primary raw material ferrite is made by using iron oxide and strontium carbonate.

Ceramic hard ferrite materials.

Ceramic magnets are manufactured using powder technology techniques. Ceramic 1 hard ferrite an isotropic dry pressed ferrite material which may be magnetized in any direction. They are electrically nonconductive meaning that they are insulators and ferrimagnetic meaning they can easily be magnetized or attracted to a magnet. 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.

The raw materials used to produce ferrite magnets are strontium carbonate and iron oxide both of which are readily available and low in cost. Home material grades hard ferrite ceramic the chemical composition of ferrite magnets is sro 6 fe2o3 strontium hexaferrite. These materials are mixed together and then elevated in temperature to 1800 2000 degrees f. The major raw materials used to manufacture ceramic magnets are iron oxide commonly known as rust and strontium carbonate.

Typical applications include latches axial magnetic couplings for water meters frictionless bearings for watt hour meters stepper motors magnetic sensors ie. They exhibit higher levels of magnetic force than do ceramic 1 materials. Grades 5 and 8 ceramic materials are anisotropic and must therefore be magnetized in the manufactured dimension. A ferrite is a ceramic material made by mixing and firing large proportions of iron iii oxide fe 2 o 3 rust blended with small proportions of one or more additional metallic elements such as barium manganese nickel and zinc.
