Ceramic Magnet Wikipedia

They are electrically nonconductive meaning that they are insulators and ferrimagnetic meaning they can easily be magnetized or attracted to a magnet.

Obsolete 9 ghz magnetron tube and magnets from a soviet aircraft radar. The crystallinity of ceramic materials ranges from highly oriented to semi crystalline vitrified and often completely amorphous e g glasses. A ceramic is any of the various hard brittle heat resistant and corrosion resistant materials made by shaping and then firing a nonmetallic mineral such as clay at a high temperature. Rare earth magnets are strong permanent magnets made from alloys of rare earth elements developed in the 1970s and 1980s rare earth magnets are the strongest type of permanent magnets made producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.

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. What is a ceramic magnet ceramic magnets also known as ferrite magnets were developed in the 1960 s as a low cost alternative to metallic magnets. The magnetic field typically produced by rare earth magnets can exceed 1 4 teslas whereas ferrite or. A magnet is a material or object that produces a magnetic field this magnetic field is invisible but is responsible for the most notable property of a magnet.

They are composed of iron oxide and strontium carbonate. Common examples are earthenware porcelain and brick. While their hard brittle quality and low energy exclude them from some applications ceramic magnets have won wide acceptance due to their corrosion and demagnetization.
