Ceramic magnets are permanent magnets made up of a composite of iron oxide and barium/strontium carbonate. Through pressing and sintering ceramic magnets are made. These magnets are also made in different grades. They are widely used magnets with good magnetic strength and resistance to demagnetization. The color of ceramic magnet is charcoal gray and they normally appear in the forms of discs, rings, blocks etc.
Features
Since the ceramic refrigerator magnets are hard and brittle in nature therefore for their finishing they require diamond cutting or cutting wheel.
They can acquire only simple shapes.
These magnets have excellent intrinsic coercive force.
As compare to other rare earth and alnico magnets they are less expensive.
They are available in different grades like 1, 5, 8 of which grade 8 is the strongest.
Ceramic magnets have low service temperature as compared to rare earth magnets.
