【摘要】 根据计算机模拟的预期结果,通过适当控制配方和工艺参数,获得了具有明显“双峰效应”介电特性的陶瓷材料,并制备成功符合彩电要求的低损耗中高压陶瓷电容器。有关的介电性能检测、微观结构分析、显微形貌及其微区元素分析的结果表明,在此陶瓷体内可能存在“两相结构”与“壳芯结构”共存的化学不均匀分布状态。更多还原

【Abstract】 Accrding to the results of imitation, a type of ceramic dielectric materials has been developed which presents the double-peak effect and satisfies the domestic demand of color television set. It is shown that there is a coexist ence of the two-phase structure and she11-core structure in a chemically inhomogenuously disttributed state in the SrTiO₃-based ceramic dielectric material by means of XRD, SEM, STEM, EDAX and dielectric determination.更多还原
