high-density ferrite member and ferrite beads composition therefor

摘要

The present invention is by applying a high-density ferrite member, and relates to a ferrite bead composition therefor, and more particularly, after being fabricated body of compression molding a suitable ferrite beads composition for compression molding ferrite, sogyeolga heat treatment, a useful sintering as electromagnetic materials It relates to a process to obtain a ferrite member. The method comprising the steps of:; Forming a ferrite bead from the ferrite particles and an organic binder compound; And; For example, sorbitan mono-or steps of uniformly mixing the expensive and limited amount of fatty acid ester of a compound such as hexyl sitan kwiol access rate to the ferrite bead;; It includes. Ferrite bead composition of the present invention, for example, even for a low number of pressure and the characteristics of the ferrite body as advantageous with respect to the development of compression molding, such as the reduction of the spring back phenomenon that, in addition, after sintering from the compression-molded article a high density and the mold glass Do.
