摘要： 采用流延成型工艺制备了Pb(Ni1/3Nb2/3)O3基铁电陶瓷与NiZnCu铁氧体叠层复合体,研究了两种材料的低温共烧兼容特性,结果表明,两种材料之间不会发生化学反应产生新的物相,二者具有良好的化学相容性;两种材料于950℃下烧结可获得无翘曲变形、无分层开裂、界面结合良好的叠层共烧体;对叠层共烧体微观组织结构分析表明,靠近界面处介电材料晶粒尺寸与远离界面处晶粒尺寸有差别,提出差别因子dD参数用于表征界面处微观组织形态的变化;对叠层共烧体进行淬火实验表明两种材料可以良好的共烧在一起,并形成强结合的界面.

Abstract: The multilayer composites were prepared by cofiring Pb(Ni1/3Nb2/3)O3 based ferroelectrics and
NiZnCu ferrite. Their interaction, cofiring properties and interface microstructure were investigated. The difference factor dD
was proposed to describe the microstructure difference between the interface and the inner parts. The results show that there is no chemical reaction exsting
between the ferroelectrics and ferrite materials. The multilayer composites cofired by ferroelectrics and ferrite at low temperature
(950℃) with no camber and crack defects can be successfully prepared. The grain of ferroelectrics adjacent to the interface is
larger than that far from the interface. The interface bonding property of the multilayer composites testified by quenching into water from 500℃
to room temperature, showing no cracks or delaminations, is excellent.

Key words: ferroelectrics, ferrite, cofiring properties, multilayer composite, interface
