Ferrite Magnets

Ferrite magnets, also known as ceramic magnets, are a type of permanent magnet made from iron oxide mixed with barium or strontium carbonate. They are categorized into hard ferrite and soft ferrite magnets based on their magnetic properties and applications. Here’s an overview of ferrite magnets, with distinctions between hard ferrite and soft ferrite magnets:

• Composition: Primarily composed of iron oxide (Fe2O3) combined with barium carbonate (BaCO3) or strontium carbonate (SrCO3).
• Manufacturing Process: Produced by a powder metallurgy process, including mixing, pressing, and sintering.
• Magnetic Properties: Offer moderate magnetic strength, good resistance to demagnetization, and excellent corrosion resistance.
• Cost: Economical to produce, making them a popular choice for many applications.
