【摘要】 本文选择ZnO和Pb(Mg13Nb23)O3为基体材料,利用轧膜技术制备了多层片式结构的压敏电容双功能陶瓷元件。通过工艺因素和SEM微观形貌分析,研究了ZnO基压敏材料和Pb(Mg13Nb23)O3基电容材料的制备过程、热行为匹配性、微观结构等在制备多层结构中的作用。以仿独石工艺形成了具有压敏-电容双功能的陶瓷元件,获得了降低元件压敏电压和提高其电容量的有效途径,为此类材料的应用打下研究基础。更多还原

【Abstract】 A Novel Varistor-Capacitor Multilayer Ceramic Device was fabricated using rolling techniques. The ZnO-based materials and Pb(Mg_1/3Nb_2/3)O₃-based materials were chosen as the respective varistor and capacitor components. A comprehensive study of the materials selection, processing, match of sintering, microstructures of a multilayer varistor/capacitor（MLVC） device has been presented. Prototype MLVC devices are prepared by simulative MLC method, which indicated good electrical properties that can be tailored by changing the layer number. Future applications of this kind of devices can be based on this work.更多还原
