Abstract

In this paper, the hollow sphere Fe₃O₄ powders pepared by the solvothermal method were mixed with Co nanoparticles (prepared by arc-discharge, the size about 100nm), the quality ratio of Fe₃O₄ and Co is 4:1. The SEM study shows that the Fe₃O₄ powders have Hollow sphere structural with the size of about 200nm. As a result, when Co nanoparticles are introduced, Fe₃O₄/Co composite absorbent is obtained enhanced microwave absorption properties, which is attributed to the improved synergistic effect of dielectric and magnetic components between ε_r and μ_r. The results show that Fe₃O₄/Co composite absorbent is great potential microwave absorbents for practical applications.
