Abstract

Ferric oxide, that is a principal raw material of ferrite, contains anions as impurities. Since it is generally produced from iron chloride or iron sulfate solution obtained from waste liquid of acid cleaning. In this paper, the effects of anions on sintering behavior of NiCuZn ferrite were investigated. The sintered densities of NiCuZn ferrites were not effected by the addition of anions. However the beginning temperatures of shrinkage were slightly shifted to higher temperature. The diffusion mechanism at initial stage of sintering changed from grain boundary diffusion to bulk diffusion by the addition of anions. Reaction products of CuO and anions could change the diffusion mechanism.
