摘要
首先用sol-gel法制得了Pb0.95Sr0.05(Zr0.52Ti0.48)O3纳米粉料(简称PZT),然后采用固相反应法制备了ζ(PZT:NiCuZn)为1:9和3:7的两种复合材料。研究Ni0.26-xCu0.19+xZn0.55Fe2O4铁氧体的组成对低温烧结复合材料的显微结构、电磁性能的影响。结果表明:当x=0.02的化学组成为主配方时,复合材料可实现900℃低温烧结,且ζ(PZT:NiCuZn)为1:9的复合材料的μi高达92,Q值为39,ε′为19;而ζ(PZT:NiCuZn)为3:7的复合材料的μi为26,Q值为19,ε′为32。
Firstly, PZT [Pb0.95Sr0.05（Zr0.52Ti0.48）O3] nanopowder was prepared by sol-gel method. Then PZT/NiCuZn composite materials were prepared by a solid-state reaction method, which PZT and NiCuZn mass ratios were 1：9 and 3：7, respectively. Effects of Ni0.26.xCu0.19＋xZn0.55Fe2O4 ferrite compositions on the microstructures and electromagnetic properties of low temperature sintering composite materials were investigated. The results show that the composite materials can be sintered at 900℃. When x = 0.02, and for the composite materials of 1：9 mass ratio, initial permeability is 92, Q-value is 39, ε＇ is 19, while the composite materials of 3：7 mass ratio, initial permeability is 26, Q-value is 19 and ε＇ is 32.
