摘　　要：首先用sol-gel法制得Pb0.95Sr0.05(Zr0.52Ti0.48)O3(PZT)纳米粉料,然后用固相法制备NiCuZn/PZT铁氧体/陶瓷复合材料,研究了P2O5-Bi2O3复合掺杂对复合材料微观结构及电磁性能的影响。结果表明:当w(Bi2O3)=2.5%时,引入适量的P2O5,不仅可使品质因数Q值提高到55,同时起始磁导率和烧结体密度分别提高到19和6.01g/cm3,介质损耗下降到0.025。其电磁性能满足电容器和电感器件的制作要求,有望成为用于叠片式滤波器的电感、电容复合双性材料。Firstly, Pb0.95Sr0.05（Zr0.52Ti0.48）O3 （abbreviated as PZT） nanopowder was prepared by a sol-gel method. Then NiCuZn/PZT ferrite/ceramic composite materials were fabricated using solid state reaction method. Effects of P2O5-Bi2O3 co-doping on the microstructure and electromagnetic properties of NiCuZn/PZT composite materials were investigated. When doped mass fraction of Bi203 is 2.5%, the proper additions of P2O5 not only make the quality factor increase to 55, but also the initial permeability and bulk density increase to 19 and 6.01 g/cm3 respectively, and the dielectric loss decreases to 0.025. The electromagnetic properties of composite materials can satisfy the production requirements both of capacitors and inductors. It is promising as a candidate of new multilayer chip filter with inductor and capacitor dual performance.
