About Ferrite Disc Magnet

An 8x3 ferrite disc magnet is a cylindrical permanent magnet with a diameter of 8 mm and a thickness (height) of 3 mm, made from ferrite ceramic material, typically barium ferrite (BaFeO) or strontium ferrite (SrFeO). These magnets are widely used for their cost-effectiveness, chemical stability, and moderate magnetic strength in industrial, electronic, and consumer applications.

Material and Composition

The 8x3 ferrite disc magnet is a hard ceramic magnet produced by powder sintering. Its main components include:

Iron Oxide (FeO) 7075% by weight, forms the magnetic ferrite lattice and provides the fundamental magnetic properties.
Strontium Carbonate (SrCO) or Barium Carbonate (BaCO) 2530% by weight, stabilizes the crystal structure and enables permanent magnetism.
Minor additives (02%) such as TiO or CoO, may be added to improve sintering, surface quality, or mechanical strength.

The powders are pressed into the disc shape and sintered at high temperatures (12001300C) to produce a dense, hard, and brittle magnetic ceramic. The surface is typically matte or semi-smooth, and the disc may be coated or painted for corrosion protection, though ferrite is naturally resistant to most chemicals.

Key Characteristics

Permanent Magnetism: Retains magnetization without an external power source.
Magnetic Strength: Moderate, suitable for holding, sensing, or low-cost magnetic assemblies.
Brittleness: Hard but brittle; prone to chipping or cracking under mechanical impact.
Chemical Resistance: Excellent resistance to corrosion, moisture, oils, and most acids or alkalis.
Electrical Insulation: Non-conductive, safe for use in electronic assemblies.
Temperature Stability: Operates effectively up to 250C without significant loss of magnetic performance.
