Influence of Ta2O5 Additive on Microstructure and Magnetic Properties of NiCuZn Ferrites

doi:10.3724/SP.J.1077.2014.13463

Abstract

Abstract:

NiCuZn ferrites doped with Ta₂O₅ additive were prepared by solid-state reaction method. The influence of Ta₂O₅ additive on the microstructure, static magnetic properties and high frequency losses (P_cv) of NiCuZn ferrites were investigated. The results reveal that Ta₂O₅ can refine the grain of NiCuZn ferrites, and consequently reduce the sintering density. At the same time, the saturation induction and initial permeability of samples reduce monotonously with the increase of Ta₂O₅ content. The coercive force and resonance frequency, however, increase gradually. Furthermore, the high frequency losses (P_cv) firstly decrease and then increase, and the dominant factor of P_cv transforms from residual loss (P_r) to hysteresis loss (P_h), so the P_cv has a valley value when Ta₂O₅ content is 0.12wt%. The lowest P_cv is 139 mW/cm³ at the conditions of 100℃, 3 MHz and 10 mT, where P_h and P_r are 93 mW/cm³ and 46 mW/cm³, respectively.

Key words: NiCuZn ferrite, Ta₂O₅ additive, microstructure, high frequency losses
