中文摘要：
微波介电陶瓷在现代通讯中被广泛用作谐振器、滤波器等元器件，是现代通信技术的关键基础材料，在现代通讯工具的小型化、集成化过程中正发挥着越来越大的作用。本项目首先对B位缺位类钙钛矿A4B3O12型陶瓷的结构与微波介电性能进行系统研究，然后通过Li离子填隙控制B位空位的浓度并采用不同电价与半径的离子在氧八面体内(A位)、外（B位）的复合对材料的结构与性能进行探索性的调控研究。借鉴与对比复合钙钛矿型基陶瓷的研究成果与规律，从键价特性、谱学特性、氧八面体结构畸变、离子极化率变化等角度揭示不同晶体结构类型、B位的有序-无序类型及程度变化对材料微波介电性能的影响及机制，这对于指导高性能微波介质陶瓷新体系的选择与性能优化具有十分重要的科学意义与实用价值。
