Ceramic Magnet Definition

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.

Ceramic magnet definition.

Commercially prepared magnetic ceramics are used in a variety of permanent magnet transformer telecommunications and information recording applications. 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. Many ferrites are spinels with the formula ab 2 o 4 where a and b represent various metal cations usually including iron. 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. How to choose use metal separators in chicago in 1959 the company started as a stocking distributor for cast alnico magnets and small ceramic magnet assemblies designed for industrial use. Magnetic ceramics oxide materials that exhibit a certain type of permanent magnetization called ferrimagnetism. 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.

This article describes the. They are composed of iron oxide and strontium carbonate. There are two different types of ceramic magnets soft and hard magents.
