采用sol-gel法、固相反应法和掺杂的sol-gel法三种制备工艺,制备了PZT与NiCuZn质量比为3:7和4:6的两种铁电/铁磁复合材料.研究了不同制备工艺对低温烧结复合材料显微结构和电磁性能的影响.结果表明:三种制备工艺都能很好地实现900 ℃低温烧结,且所制复合材料的ρ_v大于5.2 g·cm~(-3),μ_i大于19,Q值大于265,ε′大于45.相对而言,掺杂的sol-gel法所制材料性能最好,其次是固相反应法,再次是sol-gel法.但是,从适于批量生产以及降低成本的角度考虑,固相反应法更符合实际.

Two kinds of PZT/NiCuZn ferroelectric/ferromagnetic composite, in which the mass ratio of PZT to NiCuZn were 3:7 and 4:6, were prepared through three kinds of preparation process: sol-gel method, solid-state reaction method and doped sol-gel method. The effects of preparation process on the microstructure and electromagnetic properties of obtained composites sintered at low temperature were investigated. The results show that low temperature sintering at 900℃ is applicable for all three kinds of preparation process. For all prepared composites, their bulk density are larger than 5.2 g·cm~(-3), initial permeability are larger than 18, Q-factor are larger than 265 and ε′ are larger than 45. The performance of composites prepared by doped sol-gel method is highest, while the performance of composite prepared by sol-gel method is lowest. However, the solid-state reaction method is more practical taking into account the mass production and cost of composite.
