The magnetic opening (treatment) was surrounded by four C8 Barium Ferrite (BaFe2O4) permanent magnets which measured approximately 400 Gauss at the surface. The control opening was surrounded by four clay bricks of similar size and shape to the magnetic
The barium ferrite turns into a solid block while still retaining its magnetic properties. The magnets have an excellent resistance to demagnetization, allowing them to still be useful in speaker units over a long period of time.

Strontium ferrite magnets are the most commonly used due to their better magnetic performance compared to barium ferrite and at Magnet Expert, our stock range is strontium ferrite. However, we are able to manufacture barium ferrite to order.
ferrite magnets or ceramicsare sintered permanent magnets composed of barium or strontium carbonate, and iron oxide. this class of magnets, aside from good resistance to demagnetization, has the popular advantage of low cost. the sorts of hard ferrite magnets are manifold and complete. they are charcoal gray in color and usually appear in the
Hard Ferrite (ceramic) magnets, composed of barium or strontium, were developed in the early 1960's as an alternative to the more expensive metallic magnets. This class of magnet is very hard, brittle and possesses lower energy characteristics compared to other magnetic materials.
MIXED-LAYER POLYTYPES RELATED TO MAGNETOPLUMBITE J. A. KouN eNo D. W. Ecrlnr, U. S. Army Electron,ics Laborator,ies, is known as barium ferrite and has become a commerciaily barium ferrite. Similarly, there is a block having six anion layers, two ol
Ceramic magnets, or ferrite, are made of a sintered composite of powdered iron oxide and barium/strontium carbonate ceramic. Due to the low cost of the materials and manufacturing methods, inexpensive Ceramic magnets (or nonmagnetized ferromagnetic cores, for use in electronic component such as radio antennas, for example) of various shapes can

Barium ferrite, abbreviated BaFe, BaM, is the chemical compound with the formula BaFe 12 O 19. This and related ferrite materials are components in magnetic stripe cards and loudspeaker magnets. BaFe is described as Ba 2 (Fe 3 ) 12 (O 2− ) 19 .
Barium ferrite is a chemical compound of barium and iron. It is used as a component in magnetic stripe cards. Barium is a metallic alkaline earth metal with the symbol Ba, and atomic number 56.
Ceramic (Ferrite) Discs Blocks Rings Ceramic or Ferrite magnets are made of a composite of iron oxide and barium or strontium carbonate. These materials are more readily available and at a lower cost than other types of materials used in permanent magnets.
Well, ferrite magnets are found in their simplest form as they consist of iron oxide mixed with barium carbonate or strontium carbonate. These components are heated above 1000 degree Celsius temperature in the absence of air.
