Ceramic Magnet

Ceramic Magnet: Ceramic magnets produced by mixing iron oxide and barium oxide are extensively used. Recently manufactured permanent magnet by neodymium boron iron alloy is the most powerful magnet. At first permanent magnet was prepared by nickel as well. A ceramic magnet is prepared by mixing iron oxide and barium oxide Ceramic magnets are known as ferrites.

Ceramic magnets, also known as ferrite magnets were developed in the 1960’s as a low-cost substitute for metallic magnets. They are composed of iron oxide and strontium carbonate. They are simple to magnetize. They are very defiant to deterioration and usually do not require additional coatings for deterioration protection. They are resistant to demagnetization by outside fields. They are stronger than usual magnets, though many other types of a magnet are stronger than them.

Ceramic magnets are manufactured using powder technology techniques. The main raw objects – ferrite – are made by using iron oxide and strontium carbonate. These materials are mixed together and then elevated in temperature to 1800-2000 degrees F. At this temperature, they go through a chemical change and the consequential material is ferrite.
