摘要: 使用不同的化学共沉淀法制备零维纳米γ-Fe2O3和α-Fe2O3粉体,通过比表面测试、透射电镜(TEM)和X-射线衍射(XRD)分析其结构,并在10GHz的频率下测试了它们的微波吸收性能。结果表明:实验制备得到了零维纳米γ-Fe2O3和α-Fe2O3粉体,在10GHz的频率下γ-Fe2O3的微波吸收性能比α-Fe2O3要好。Abstract: Zero dimension nanometric α-Fe2O3 and γ-Fe2O3 were prepared by chemical coprecipitation with different processes. Their structures were analyzed by using specific surface testing, transmission electron microscope (TEM) and X-ray diffraction (XRD). Finally, their abilities of microwave absorption were tested at 10GHz frequency. The results show that zero dimension nanometric γ-Fe2O3 particles have much better microwave absorption ability than α-Fe2O3.
