| 摘 要： | 先采用sol-gel法制得Pb0.95Sr0.05(Zr0.52Ti0.48)O3(PZT)纳米粉料,再采用固相反应法制备NiCuZn/PZT铁氧体/陶瓷复合材料。研究了低温烧结助剂Bi2O3掺杂对复合材料显微结构和电磁性能的影响。当w(Bi2O3)为2.5%时,NiCuZn与PZT的质量比为7:3和6:4的两种复合材料在900℃下均可实现低温烧结,其烧结体密度均大于5g/cm3。其中,7:3的μ′达到27,ε′大于34;6:4的μ′达到16,ε′大于50,均有望制作成不同性能指标的电感、电容双功能材料。

| Abstract: | Firstly, Pb0.95Sr0.05(Zr0.52Ti0.48)O3 (abbreviated as PZT ) nanopowder was prepared by a sol-gel method. Then NiCuZn/PZT ferrite/ceramic composites were prepared by a solid state reaction method. The effects of Bi2O3-doping as low temperature sintering aid on the microstructures and electromagnetic properties of composites were investigated. As the w(Bi2O3) is 2.5%, composites with mass ratio of NiCuZn to PZT of both 7:3 and 6:4 can realize low temperature sintering at 900 ℃, with the sintered bulk density of greater than 5 g/cm3. μ′ reaches 27 and ε′ is more than 34 for the former, while μ′ reaches 16 and ε′ is more than 50 for the latter. They are expected to be fabricated as inductor and capacitor double functions materials with different performance indexes. |
