ABSTRACT:
A ferrite composition containing a spinel ferrite and a small amount of a polyphenylene sulfide as a binder, which can provide a molding product having a higher initial permeability and excellent thermal, flame and arc resistances. The molding product is prepared by molding the composition at an elevated temperature under pressure. The use of a ferrite mixture of particle groups having different particle size distributions within the particle size range of 100.mu. to 5 mm. is preferred.
