저손실 첨가제가 NiCuZn Ferrite 특성에 미치는 영향 연구
A Study on the Effect of Low-loss Additives on the Property of NiCuZn Ferrite
E-mail:
The electromagnetic properties and microstructures of the ferrites based on ( )() were investigated by changing the amount of additive SnOand CaO and the sintering temperatures. Addition of caused pores in the specimen. There was no variation of grain size by changing the amount of additives. Total loss was reduced when ( ) () composition was sintered at rather than . Addition of CaO was useful to reduce the total loss because it increased the sintering density. The lowest total loss was obtained when 0.06 wt% and 0.4 wt% CaO were added at the same time.
