【摘要】 以聚丙烯酸酯乳液为粘合剂,采用水基流延成型制备镍电极多层陶瓷电容器(Ni-MLCC)。研究了水性粘合剂适合X7R瓷粉流延成型的粘度特性和热稳定性,用扫描电子显微镜(SEM)分析了所得膜片和电容器的微观结构,并对所制备电容器的电性能进行了测试。结果表明:水性聚丙烯酸酯粘合剂具有剪切稀薄的粘度特性,热分解温度低,能够满足流延成型的需求。水基流延成型制备膜片表面光滑,无缺陷,瓷粉在粘合剂中分散均匀。所制备Ni-MLCC的电极连续性好。更多还原

【Abstract】 Ni electrode-multilayer ceramic capacitor(Ni-MLCC) was prepared by aqueous tape-casting of X7R with acrylic emulsion as binders.Viscosity properties and thermal stability of acrylic binders were investigated.Scan Electronic Microscope(SEM) was used to analysis microstructure of green sheets and Ni-MLCC.Electronic properties of Ni-MLCC were also tested.The results showed that(aqueous) acrylic binders had shear-thinning properties suitable for tape-casting of ceramic powders.And low decomposition temperature was another good property for preparing Ni-MLCC.The green sheets had smooth surface without defect.Ceramic powders were dispersed uniformly in green sheets.The electrode of Ni-MLCC had excellent continuity.更多还原
