Abstract

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 (ε_r=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.
