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.
