研究了不同BaCu（B2 O5）（BCB）掺杂量对2．5ZnO-2．5Nb2 O5-5TiO2（ZNT）陶瓷烧结行为、介电性能及与 Ag相容性的影响规律。添加BCB可有效地将ZNT陶瓷的烧结温度从1100℃降低至900℃。BCB添加量为3．0wt％，900℃烧结3 h所制得的ZNT陶瓷的微波性能良好：εr＝48，Qf＝15258 GHz，τf＝41×10-6/℃。且在BCB掺杂ZNT陶瓷与 Ag共烧样品中未检测到新生相和 Ag的扩散，表明3．0 wt％BCB掺杂的ZNT陶瓷与 Ag的相容性良好，是一种很有潜力的 LTCC材料。“,”The effects of different doping amounts of BaCu(B2 O5 )(BCB)on the sintering behavior,dielectric properties and compatibility with Ag of 2.5ZnO-2.5Nb2 O5-5TiO2 (ZNT)ceramics were investigated.The sintering temperature of ZNT ceramics was effectively lowered from 1 100 ℃ to 900 ℃ with BCB addition.3.0wt% BCB doped ZNT ceramic specimens sintered at 900 ℃ for 3 h exhibit optimum dielectric properties with values ofεr=48, Qf=15 258 GHz,τf=41×10-6/℃.Furthermore,no second crystalline phase and no silver migration were detec-ted in the BCB-doped ZNT ceramic specimen co-fired with Ag,which indicates that 3.0wt% BCB doped ZNT ceramics could be a suitable candidate for LTCC applications.
