Strontium Ferrite (SrO.6Fe2O3) magnets and Barium Ferrite (BaO.6Fe2O3) magnets are the two types of ceramic Ferrite magnet. The Strontium Ferrite magnets are the most commonly manufactured due to having stronger magnetic properties. The Ferrite magnets (Ceramic magnets) have a characteristic "pencil lead" colour (i.e. a dark grey colour).

3.1 Introduction. The word 'ferrite', derived from the Latin 'ferrum' means iron. The first type of magnetic material known to human was lodestone which is made up of the ore magnetite (Fe 2 O 3 ). Ferrite is a ceramic material made by mixing iron oxide with a metallic element. They are electrically non-conducting insulators.
