Ceramic magnets are generally the most favored materials from which magnets are made. A ceramic magnet is made using powdered magnetic materials, such as iron oxide (Rust) and Strontium carbonate.
Ferrites having a high magnetic absorptiveness, which enables them to amass magnetic fields stronger than iron, are referred to as Ceramic magnets. Generally, they are inflexible and brittle usually appearing in the shapes of cubes, cylinders, motor arcs
The formation, uses and advantages
A ceramic magnet is obtained by the amalgamation of two main materials. Through a process called Sintering, they are heated and melted down to such a point where they adhere to each other. Once that happens, the material is cooled, condensed into a certain shape dried and then sintered one last time.
Magnets such as these hold benefits of longevity and cost. They tend to withhold their magnetic capabilities for long periods and are thus, also called as permanent magnets. The raw materials required for making magnets is easily available in abundance at cheap prices for mass-production, immensely reducing the costs.
This combination has proved to increase the reputation of this variety of magnet. Uses of ceramic magnets run the enterprise from the mundane to the technical. The flexibility of magnets and their capacity to ensure their magnetization is the key to all of these applications.
Ceramic magnets are exclusive because of their use in flexible fabrics, for ornamental purposes, crafts and other usages in homes, educational and industrial institutions. Ceramic magnets have a boat-load of uses. They are commonly found in Sound systems, automobiles, medical equipments such as MRI machines, DC motors and several magnetic powered machines such as holders, lifters and separators along with industrial assemblies and tools.
All magnets can be custom-made to suit individual needs and ceramic magnets are no exception. Whether you are a fabricator who needs a particular magnet mass produced, an institution looking to use magnets for a one time project, or an individual who needs a magnet for use in the home, ceramic magnets are easily adjustable and customizable for any type of job you have in mind.
The disadvantages of Ceramic Magnets
Despite all the pros, there are some cons to the magnets as well. However Mass production of these magnets limits the variety of shapes it can moulded into. Most commonly, they are available in bar, cube, discs and ring shapes.
In certain circumstances, the magnetic capabilities may need to be minimized or to bluntly put it, be turned off whenever necessary. The problem is this cannot be done with ceramic magnets.
