Hard Ferrite (ceramic) magnets, composed of barium or strontium, were developed in the early 1960's as an alternative to the more expensive metallic magnets. This class of magnet is very hard, brittle and possesses lower energy characteristics compared to other magnetic materials.
Ceramic magnets are composed of strontium carbonate and iron oxide. They are also called ferrite magnets, which are featured by rigidity and brittleness. In terms of magnetic properties, these ferrites are often classified into soft or hard ones.
Ferrite permanent magnets exist in two forms Strontium Ferrite magnets and Barium Ferrite Magnets. The Strontium Ferrite Magnets is the most common. Ferrite magnets are darker grey in colour and are often referred to as having a "pencil lead" appearance. Ferrite / Ceramic permanent magnets are technically known as hard ferrite materials .
