摘　　要：温度稳定型钛酸钡基介电材料具有良好的性能,然而做为MLCs瓷料时,烧结温度偏高.用固溶体Ba1-xCdxTiO3替代BaTiO3做为基料,可以有效地降低烧结温度,制备符合X7R标准的MLCs瓷料,获得较高的室温介电常数.The BaTiO3 based temperature stable dielectric materials have been sintered at relevant high temperature to make MLCs. In this study, based on Ba1-xCdxTiO3 to replace BaTiO3, the sintering temperature was decreased efficiently. The MLCs materials meeting EIA X7R specifications were obtained, which were sintered as low as 1150℃ and had relevant high dielectric constant at room temperature.
