摘要
研究了用Al ̄(3+)代替Fe ̄(3+),对高频大功率NiZn铁氧体性能的影响,它有效抑制了Fe ̄(2+)的产生。使铁氧体电阻率增加,介电损耗和磁损耗下降,且有较大的摆幅磁感,是提高高频大功率NiZn铁氧体性能的有效方法。
In this paper,we have studied theinfluence of Al ̄(3+) instead of Fe ̄(3+) on the properties ofNiZn ferrite in the field of high-frequence and large-power. When using Al ̄(3+) instead of Fe ̄(3+),Fe ̄(2+)is restrainted,the electrical resistivity of ferrite isincreased、magnetic and dielectric loss are decreased。and the flux swing becomes large.This is aneffective mathod to improve the liroperties of NiZnferrite .
