摘要
为了解决多层片式LC滤波器制造中的介电体与铁氧体的共烧问题,采取了在两种材料之间加入中间层复合材料的方法来实现异种材料之间的共烧。制备了由Pb(Ni1/3Nb2/3)O3-PbTiO3基介电体和NiZnCu铁氧体构成的中间层复合材料,研究了其显微组织、成分分布以及其与介电体和铁氧体的共烧界面等,结果表明中间层复合材料中介电体与铁氧体各自保持独立的相结构,没有新相生成;介电体晶粒与铁氧体晶粒相间分布于中间层中,且它们之间存在着离子的相互扩散;中间层能够有效地减小异种材料共烧界面上的应力。
Intermediate layer composites consisting of PNN-PT ferroelectrics and NiZnCu ferrite were prepared to realize the cofiring of ferroelectrics and ferrite for the manufacture of multilayer chip LC filters. The microstructure of intermediate layer composites and the interfaces between the composites and PNN-PT and NiCuZn ferrite were investigated. The results show that ferroelectrics phase and ferrite phase coexist in the intermediate layer ceramics, and no new phase appears. But ion interdiffusion is detected between ferroelectrics phase and ferrite phase. The intermediate layer composites are effective to eliminate the interfacial defects and can be used to join the ferroelectrics and ferrite.
