Ceramic magnets are also known as hard ferrites or ferrite magnets, which are composed of primarily iron oxide, Fe2O3. The two common compositions are: strontium ferrite, SrFe12O19 (SrO·6Fe2O3) and barium ferrite BaFe12O19 (BaO·6Fe2O3). Soft ferrites have lower coercivity and the common compositions are manganese-zinc ferrite (MnZn, with the formula MnaZn(1-a)Fe2O4) and nickel-zinc ferrite (NiZn, with the formula NiaZn(1-a)Fe2O4).

Anisotropic Ceramic Square Magnet 50X50X10mm
Sintered Ferrite is called the work horse of the magnet industry. It contains critical materials such as iron, strontium/barium, and some binding agents. It is made like dishes and fired at high temperature. It is more flux for the bucks than any other material. The majority of ferrites are produced in China. Applications include loudspeakers and motors. Strong C12 Grade Anisotropic Ceramic Block Rectangle Magnet
CERAMIC
CERAMIC PERMANENT MAGNETS ARE AN ECONOMICAL CHOICE FOR A WIDE RANGE OF APPLICATIONS. CERAMIC MATERIALS PRODUCE STRONG MAGNETIC PROPERTIES, AND IS AVAILABLE IN CUSTOMIZABLE SHAPES AND SIZES.
Strong Ceramic magnets can be either isotropic or anisotropic. Isotropic ceramic magnets can be magnetized in any direction while the anisotropic ceramic magnets can only be magnetized through the easy axis (magnetization direction). They have very high electrical resistivity (around 106 Ohm-cm) and positive reversible temperature coefficient of intrinsic coercivity. Permanent Block Rectangular C1 Ceramic Magnets
Ceramic maximum energy product, (BH)max, is lower than other permanent magnets, so they are typically much larger magnets in actual application. By weight, they are the most widely used magnet globally. Ceramics are chemically stable and the least expensive magnets due to inexpensive raw materials and processes. Maximum energy product, (BH)max, of 1 to 4 MGOe, is lower than that of rare earth magnets but intrinsic coercivity, Hci, from 2500 to 4000 Oersteds, (higher than Alnico). Ceramic magnets are a cost-effective choice in many industrial applications. Block Rectangular Hard Ferrite Permanent Magnets, Rectangle Bar C5 Anisotropic Ceramic Magnet
