【摘要】 采用湿法拉膜成型工艺,以收缩率大的(Zn_0.7Mg_0.3)TiO₃（简称ZMT3）材料作为夹层材料,以收缩率相对小的铁氧体材料(Ni_0.8Zn_0.12Cu_0.12)Fe_1.96O₄（简称NZC）作为两边收缩控制层,获得"三明治"叠层结构.以独特的零收缩差技术,制备了界面结合紧密,无翘曲变形、开裂等缺陷,可于900℃烧结的"三明治"结构叠层共烧体,其最佳介电性能为:ε_r=12,tanδ=9.84×10^-4.这项新技术的提出,为解决异种材料共烧时所经常产生的翘曲、变形等缺陷提供了一种新的解决思路.更多还原

【Abstract】 A novel zero-shrinkage-difference technique was introduced to eliminate the camber or cracks in cofired composites without the degradation,A sandwich structure of(Zn_0.7Mg_0.3)TiO₃（ZMT3） dielectric/(Ni_0.8Zn_0.12Cu_0.12)Fe_1.96O₄（NZC）ferrite multilayer composite was designed and prepared by using tape-casted technique,with ZMT3 as interlayer,and NZC as top and bottom layers.The produced sandwich structure shows no camber and cracks after being co-sintered.The cofired samples exhibit good dielectric performance(εr=12,tanδ=9.84×10^-4),and low firing characteristics（900℃）.Due to their dielectric performance,low firing characteristics,and realizable co-firing compatibility,the sandwich structure of ZMT3 dielectric/NZC ferrite multilayer composite can serve as the promising medium materials in the multilayer LC filter.更多还原
