Ferrites are made from BaFe12O19 and SrFe12O19 as raw materials. They are manufactured through ceramic processes, and they are relatively hard and brittle materials. Due to their excellent temperature resistance, low cost, and moderate performance, ferrites have become the most widely used permanent magnets. Ferrites have high magnetic properties, good temporal stability, and low temperature coefficients. Ferrites are widely used in various fields, including electric meters, instruments, motors, automatic control systems, microwave devices, radars, and more. Ferritic magnetization direction: can be axial, radial, or magnetized as required. Ferritic Magnet Shapes: Cylindrical, Circular, Cuboidal, Flat, Tile, and Axe-shaped. Ferrites are also known as ferroxides or magnetic ceramics. They are a class of non-metallic magnetic materials. They are composite oxides (or normal iron(III) acids) of ferric oxide with one or more metal oxides. Ferrites have magnetic properties, and at high frequencies, they have higher magnetic conductivity (higher than metal magnetic materials). Their resistance is much higher than that of metal magnetic materials, and they also have higher dielectric properties. Magnetite FeO·Fe2O3 is the simplest ferrite. Ferrites are usually limited to those composed of elements with unpaired d-layer or f-layer electrons, especially divalent metal ions with radii close to that of the divalent iron ions, such as manganese, zinc, copper, nickel, magnesium, cobalt, etc., or lanthanide elements or ions of gallium, aluminum, bismuth, barium, strontium, etc.
