Ceramic Magnet Definition

Many ferrites are spinels with the formula ab 2 o 4 where a and b represent various metal cations usually including iron.

Ceramic magnet definition.

The coercivity of the magnets are what determine what type soft magnets have low coercivity while hard magnets have high coercivity. 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. 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. Ceramic magnets are man made magnets made out of iron oxide and strontium carbonate.

They are electrically nonconductive meaning that they are insulators and ferrimagnetic meaning they can easily be magnetized or attracted to a magnet. There are two different types of ceramic magnets soft and hard magents. This article describes the. 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.

Commercially prepared magnetic ceramics are used in a variety of permanent magnet transformer telecommunications and information recording applications. Ferrites are chemical compounds ceramic with iron iii oxide fe 2 o 3 as their principal components many of them are magnetic materials and they are used to make permanent magnets ferrite cores for transformers and in various other high tech applications. Some ceramic magnet models are effective in removing relatively large ferrous objects such as nuts bolts staples and welding rods from a dry product flow.
