摘要
用复合掺杂的方法制备了高性能的高磁导率MnZn铁氧体材料。研究了Nb2O5-P2O5复合掺杂对MnZn铁氧体微观结构及磁性能的影响。结果表明,适量的Nb2O5-P2O5复合掺杂有利于促进晶粒均匀致密,提高材料的起始磁导率,降低损耗。在配方中,当ζ(Nb2O5∶P2O5)为2∶8时,起始磁导率可达到11 823。
High initial permeability Mn-Zn ferrite was prepared by composite doping method. The effects of Nb2O5-P2O5 addition on the microstructure and magnetic properties of Mn-Zn ferrite were investigated. It is found that a proper amount of mixed Nb2O5-P2O5 addition could improve uniformity of crystalline grains and initial permeability and decrease the power loss With 0.1 mass fraction Nb2O5-P2O5 addition （Nb2O5 ： P2O5 = 2 ： 8）, initial permeability of 11 823 is obtained.
