| 摘 要： | 为获得高磁导率MnZn铁氧体材料,研究了P2O5掺杂对MnZn铁氧体微观结构及电磁性能的影响.少量掺杂可使铁氧体晶粒尺寸增大,均匀性改善,起始磁导率提高.但若掺杂过量,晶粒中气孔率增加,起始磁导率下降,损耗也大为增加.在配方为(Zn0.454Mn0.493Fe2 0.053 )Fe23 O4的材料中,当P2O5掺杂量为0.10wt%时,起始磁导率可达10345.

| Abstract: | To get high initial permeability soft magnetic material, we examined the effect of added P2O5 on the microstructure and magnetic properties of MnZn ferrite. We can conclude that a small quantity of P2O5 addition could increase the diameter of crystalline grains, improve uniformity and initial permeability. If excessive P2O5 is added, porosity and core losses increase, and the initial permeability decreases. With 0.10wt% P2O5 addition in (Zn0.454Mn0.493Fe2+0.053 ) Fe23+O4 , initial permeability of 10345 is obtained. |
