Ceramic Hard Ferrite Materials

These materials are mixed together and then elevated in temperature to 1800 2000 degrees f.

Ceramic hard ferrite materials.

Grades 5 and 8 ceramic materials are anisotropic and must therefore be magnetized in the manufactured dimension. Hard ferrite magnets have excellent corrosion resistance and have normal operating capabilities between 40 c and 250 c. They exhibit higher levels of magnetic force than do ceramic 1 materials. Home material grades hard ferrite ceramic the chemical composition of ferrite magnets is sro 6 fe2o3 strontium hexaferrite.

Ceramic 1 hard ferrite an isotropic dry pressed ferrite material which may be magnetized in any direction. 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. The primary raw material ferrite is made by using iron oxide and strontium carbonate. At this temperature they undergo a chemical conversion and the resulting material is ferrite.

Ceramic magnets are manufactured using powder technology techniques. 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. Field magnets for reed switch actuators electron beam correction and.
