中文摘要： 低温共烧陶瓷（LTCC）技术是一种三维立体组装的无源器件集成及无源有源器件混合集成技术，以其优异的电子、热机械及互联特性成为目前电子元件集成化和模组化的主流方式。但现阶段商业化的LTCC材料还面临两个亟待解决的问题：其一，种类较为单一，在性能上没有实现系列化，限制了可开发器件的种类；其二，异质材料的共烧匹配问题增加了高密度集成的难度。陶瓷/铁氧体复合材料因兼有灵活可调的电性能和磁性能，为解决上述问题提供了新的思路。本项目从研究高性能、高熔点钛酸钡基陶瓷/NiCuZn铁氧体复合材料的低温烧结机制和性能入手，旨在通过对原体系进行多元掺杂和微结构控制合成适用于LTCC工艺的新型复合材料，并探索电磁性能随组分变化的分配规律，建立合适的理论模型，为复合材料性能的体系化提供依据。在此基础上，借助调整陶瓷相成分来减少助熔性杂质的用量，尝试实现复合体系的"自助熔"，进一步提高体系电磁性能。

英文摘要： Low temperature cofired ceramic (LTCC) technology, as a kind of passive or passive-active hybrid integration technology in 3D package, is gradually becoming the main way of integration and modularization for electronic components because of its excellent electronic, thermal mechanical reliability and interconnection properties. However, there are two problems needed to be solved urgently for the commercial LTCC materials. Firstly, the development of electric devices has been restrained by less kind of materials with systematism properties. Secondly, the matching ability of cofired dissimilar materials increases the difficulty to high density integration. The ceramic/ferrite composite materials provide a new method to solve the above problems due to their tunable dielectric and magnetic properties. This project starts with the research on low temperature sintering mechanism and properties of the barium titanate ceramic/NiCuZn ferrite composites with high melting point and good performance.It aims to synthesize the novel composite materials adapting to the LTCC process by multiple doping and microstructure control of original system, and explore the distribution law of electromagnetic properties with composition, and establish appropriate theoretical models to provide guidance for systematism of properties of the
