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Co2O3-Bi2O3复合掺杂对复合材料性能的影响。结果表明:当w(Bi2O3)=2.5%时,引入适量的Co2O3掺杂不仅可使品质因数提高到235,同时介电常数和烧结体密度分别提高到55和5.01g/cm3,介质损耗下降到0.065。其电磁性能满足电容器和电感器的制作要求,有望成为用于叠片滤波器的电感、电容复合双性材料。Firstly, Pb0.95Sr0.05（Zr0.52Ti0.48）O3 （abbreviated as PZT ） nanopowder was synthesized by a sol-gel method, Then NiCuZn/PZT ferrite/ceramic composites were prepared by a solid state reaction method. Effects of Co2O3-Bi2O3 co-additive on the properties of NiCuZn/PZT composites were investigated. When the Bi203 doped amount is 2,5% （mass fraction）, the proper additions of Co203 not only make the quality factor increases to 235, but also the permittivity and bulk density increase to 55 and 5.01 g/cm^3 respectively, and the dielectric loss decreases to 0.065, The electromagnetic properties of composites 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.
