Abstract: Ferromagnetic particles with a high-temperature and thermally stable insulating coating are described. The ferromagnetic particles are first coated with a thin layer of a high permeability metal (nickel) by an electroless plating process. The deposited metal layer is then oxidized by controlling the time and temperature while heating the coated particles in an oxygen atmosphere. This process develops a thin and uniform layer of metal oxide on the ferromagnetic particles. The controlled oxidation of the coating helps encapsulate the particles with a thermally stable and electrically non-conducting layer. These particles can then be compacted and then annealed above 500 degrees Celsius to relieve the stresses introduced in the shaping, thereby obtaining articles with a high permeability and low magnetic loss.

The high compressibility iron powder helps achieve high relative density and also allows easy path for the passage of magnetic flux.
