Molding of magnetic article e.g., magnetic core used in automotive industry involves forming encapsulated layer of ceramic material on ferromagnetic particles, compacting the particles and annealing the resultant magnetic article

摘要

A magnetic article is molded by forming an encapsulated layer of ceramic material on each of the ferromagnetic particles by combining a polymeric material with a powder of the ceramic material; compacting the ferromagnetic particles to form a solid magnetic article; and annealing the magnetic article to decompose the polymeric material.
