摘　　要：铁氧体吸波材料具有吸收频段宽、吸收率高、匹配厚度薄等优点,但由于存在密度大、频带较窄、高温特性差等问题,难以满足吸波材料"薄、轻、宽"的特性,限制了铁氧体吸波材料的应用。本文介绍了吸波材料的吸波机理及铁氧体吸波材料的研究进展,结合近几年铁氧体吸波材料的的发展现状,概述了改善铁氧体吸波材料吸波性能的方法,进而展望了吸波材料的发展前景。总结得出对铁氧体吸波材料进行纳米化、复合化、掺杂及改变形貌,进一步研究和开发出性能优良的吸波材料并将其应用到工业化生产中,是未来制备高性能吸波材料的发展方向。Ferrite absorbing materials with wide absorption band,high absorption rate,thickness, etc,but due to the existence of large density,narrow frequency band,high temperature performance and other issues,it is difficult to meet the requirement of wave absorbing materials “thin,light,wide”, limiting the application of the ferrite absorbing wave materials. This paper introduces the absorbing mechanism and research progress,summarizes the method of performance improvements,and prospects the development of ferrite microwave absorbing materials,combining the development of ferrite wave absorbing materials in recent years. The future development direction of preparation of high performance absorbing wave material is to make the ferrite absorbing materials to be nano- crystallized,composed,doped and the morphology to be changed,as well as further research and development of the excellent performance of the microwaveabsorbing material and its application to industrial production.
