摘　　要：现代移动通信技术的高速发展对各类电子设备的小型化、多功能化提出了新的要求。开发性能优良的新型磁介复合材料成为元器件小型化的解决方案之一。本工作采用固相烧结法分别合成了NiCuZn铁氧体材料以及Sr(Nb_(0.5)Al_(0.5))_(0.1)Ti_(0.9)O_(3)介电材料,然后将两者按照一定比例复合,研究了不同铁氧体/介电相含量对磁介复合陶瓷材料磁性能与介电性能的影响,并对其微观形貌与相结构进行了探究。研究结果表明,当铁氧体含量在0.7~0.8时,复合材料致密性最好,磁性能与介电性能较为优良。The rapid development of modern mobile communication technology puts more challenges on electronic device miniaturization and multifunction.Exploring new magneto-dielectric composite materials with excellent performance is one of the solutions for device miniaturization.In this paper,NiCuZn ferrite and Sr(Nb_(0.5)Al_(0.5))_(0.1)Ti_(0.9)O_(3) dielectric materials were synthesized via the solid-state reaction method.Then they were mixed in a certain proportion.The effects of different ratios between the ferrite and dielectric phases on the magnetic and dielectric properties were investigated.The microstructure was also explored.The experimental results suggest that the ferrite content is 0.7-0.8,at which fully densified morphology and superior magnetic-dielectric performance are obtained.
