Grades of Ferrite Magnets
There are about twenty-seven grades of ferrite magnets representing different magnetic properties and characteristics. Ferrite magnet grades are typically designated by combining the letter prefix Y with numbers and sometimes letters too.
Anisotropic Grades
These have been magnetized in a specific direction and display higher magnetic performance. Anisotropic ferrite magnets are used in applications requiring a specific magnetic orientation. They include Y30, Y32, Y33, Y35 and Y36.
High Temperature Grades
These ferrite magnets are particularly developed to thrive in high-temperature environments. They can withstand temperatures up to 350°C whilst maintaining their magnetic properties.
Isotropic Grades
These ferrite magnets lack a preferred direction of magnetization. They exhibit similar magnetic properties in all directions and include Y8T, Y10T,Y30H-1 and Y34.
Properties of Ferrite Magnets
Ferrite magnets have a few identifiable properties that allow their specific use in certain applications. These properties derive from their manufacturing process, inherent structure, and composition.
Coercivity (Hc)
Coercivity describes a material’s resistance to demagnetization and ferrite magnets possess high coercivity. This means that, in order to demagnetize a ferrite magnet, you require a substantial external magnetic field.
As such, ferrite magnets will tolerate factors that induce demagnetization like external magnetic fields, temperature changes and mechanical stress. Their stability under such circumstances makes them highly durable over time in which they maintain their magnetic properties.
Magnetic Permeability (μ)
This fundamental property characterizes the ease with which a material can obtain magnetic properties when placed within an external magnetic field. The magnetic permeability of ferrite magnets is high when in the presence of low to moderate magnetic fields.
This property allows their use in electromagnetic field manipulation and energy transfer applications like in inductors and transformers. In the former, they work well in electromagnetic devices where they concentrate magnetic flux lines.
Temperature Stability
Ferrite magnets display good temperature stability, maintaining their magnetic properties over a wide temperature range. They can therefore be utilized in high and low temperature extremes without loss of magnetic strength.
Ferrite magnets have high Curie temperature (Tc), which depends on the composition and grade, beyond which they become paramagnetic. They also possess a low thermal expansion coefficient, displaying low rates of expansion or contraction when temperature changes.
Electrical Insulation
Ferrite magnets do not allow passage of electric currents which is useful in applications requiring magnetic and electrical separation. As such, these magnets can be utilized where they’re integrated with electrical systems sensitive to interference.
Using ferrite magnets in electrical applications is necessary to suppress electromagnetic interference and eddy currents. Eddy currents are generated by conductive materials typically in the presence of magnetic fields.

Manufacturing Process of Ferrite Magnets
Ferrite magnets are manufactured via a powder metallurgy process thanks to its powdered raw materials. Common raw materials utilized include iron oxide and another constituent element, usually either barium or strontium carbonate.
A general overview of the manufacturing process for ferrite magnets takes the following form:
Raw Material Preparation
The primary raw material used in making ferrite magnets is iron oxide (Fe3O4). It is usually combined with either additives of strontium carbonate (SrCO3) or barium carbonate (BaCO3).
The process of raw material preparation involves carefully weighing the selected raw materials depending on the final magnet composition. A homogeneous blend is then developed by thoroughly mixing these materials.

Mixing
The mixing process ensures even distribution of the additives within the matrix of the iron oxide. There are different mixing methods including dry mixing or wet mixing which utilizes water and/or solvents. When using wet mixing, an extra process of drying is required before subsequent processing.
Dry mixing is utilized where the raw materials are in powder form blending them directly. Here, the powders are added to a mixing vessel, where they’re mechanically agitated to achieve a uniform blend.
In wet mixing, a slurry is created by adding water or a solvent to the powdered raw materials. The resulting sludge is then mixed to achieve uniform component distribution. Wet mixing can improve homogeneity and the raw materials’ chemical interaction.
Mixing equipment such as high-energy mixing mills, planetary mixers, and ribbon blenders are used to achieve thorough mixing. These mills use mechanical force to combine the materials into a single strain. When mixing, consider important parameters like mixing time and agitation speed.

Calcination
This process involves heating the mixed raw materials at a controlled temperature that can reach 1200°C. It initiates chemical reactions and removes volatile components transforming the mixture into a precursor material more conducive to sintering.
The temperature during calcination shouldn’t be too high to prematurely commence sintering. The process is ideally carried out in the presence of air or controlled atmospheres with reducing/inert gases to prevent oxidation. The process can take anywhere from several hours to a day.

Wet Milling
A wet milling process succeeds in calcination to achieve desired particle sizes for efficient density and alignment. Having reduced particle sizes enhances sintering behavior improving the final magnet’s mechanical properties.
Ball mills containing grinding media like small beads/balls of steel, ceramic, or glass materials find use in the wet milling process. The process is conducted in a controlled environment to prevent contamination and ensure consistent processing conditions.

Forming
This process is necessary to shape the ferrite magnet material into a specific shape and/or design prior to sintering. Different forming methods can be utilized including the following :
Dry Pressing: Involves the use of a mechanical press to compact the material in a mold under pressure resulting in a solid structure. It can easily execute simple and uniform shapes cost-effectively for large production volumes.
Isostatic Pressing: Here, the ferrite magnet material is placed in a flexible mold before being subjected to pressure. The pressure is by a pressurized fluid in a uniform and multidirectional manner. This forms a green compact with a near-isostatic distribution of stress capable of complex shapes.
Wet Pressing: This is typically done at between 5-15 MPa in the presence of a strong magnetic field perpendicular to the pressing direction. A slurry of the magnet material is made with the addition of a binder to enhance compression. Using plaster or silicone rubber molds treated with release agents prevents sticking. Detailed designs with intricate shapes can be achieved via this process.
Extrusion: Here, the magnetic material is forced through a die of a given shape from which it emerges as a continuous piece. This method is utilized for making magnets with particular cross-sectional shapes like tubes, rods, or custom shapes.

Sintering
The sintering process is undertaken in a high-temperature furnace where the temperature causes the particles to bond into a solid structure. During this process, the reaction of the additives and iron oxide, results in the distinctive ferrite magnet crystal lattice structure.
The densification process in sintering helps in the achievement of the desired magnetic properties. In this process, temperature and time are critical factors, the former typically ranging between 1200°C to 1300°C. Sintering time will depend on factors like material composition and equipment used.
It is characteristic to use a controlled atmosphere when undertaking sintering to prevent oxidation and undesirable chemical reactions. Gases such as hydrogen, atmospheric air, or nitrogen can be used.
A cooling process typically succeeds the sintering process upon attaining the intended sintering temperature and time. The cooling process is controlled to prevent thermal shock and cracking where the temperature is reduced to room temperature.

Machining and Finishing
Machining techniques like drilling, grinding, and cutting, are sometimes applied to sintered magnets to achieve the desired shape and surface finish. Such processes may be necessary to ensure the magnets meet the specific application requirements.
Applying surface finishing improves the appearance of the magnet, functionality and surface quality. It can include processes like abrasive blasting, polishing, sanding and lapping that help achieve specific surface texture. The method of choice depends on the desired finish and material characteristics.
Some applications may require the magnets to have protective coatings for corrosion prevention and enhanced resistance to wear. Such coatings include gold and nickel plating, and epoxy.

Magnetizing
Here, the sintered and machined ferrite magnet materials are subjected to an external magnetic field to induce permanent magnetization. The process aligns the magnetic domains in a specific direction within the ferrite material. The result is a net magnetic field featuring desired properties like polarity and strength.
Typically, ferrite magnets are manufactured in a demagnetized state preventing unintended magnetization during the process. The magnetizing equipment includes electromagnets, which generate a strong magnetic field upon the passage of electric current through a coil.
Pulsed magnetizers can also be utilized where strong magnetic fields are generated by brief, high-intensity current pulses. These are especially used when undertaking high-performance magnetization. In both instances, you can control the strength and polarity of the generated field.
When carrying out the magnetizing process, position the ferrite magnet material in the electromagnet or magnetizing fixture in the desired orientation. Polarity is determined by the applied magnetic field’s direction during magnetization.
