摘要
由ＢＺＮ 介电陶瓷与Ｎｉ－ Ｚｎ － Ｃｕ 铁氧体构成多层复合体，借助ＸＲＤ，ＳＥＭ，ＥＤＳ和ＴＭＡ等技术研究了共烧过程中两种材料界面的相互作用和共烧行为． 结果表明，共烧过程中界面元素扩散导致界面附近材料相结构和显微结构发生明显变化，两种材料烧成动力学失配造成共烧体中产生裂纹等缺陷．
A multilayer composite was prepared with BZN dielectric and Ni-Zn-Cu ferrite. The co_firing behavior and interfacial interaction between constituents during sintering were studied by using TMA, XRD,SEM and EDS techniques. The results reveal that the element diffusion across the interface results in the change in phase structure and microstructure of constituent materials. The co_firing mismatch of two constituent materials was detected and resulted in the formation of crack and lamination in the material near interface.
