High Frequency Electrical Properties of Fe/SiO2 Composites by Pressureless Sinter

摘要：

　　In this paper, Fe/SiO2 composites with different Fe content were prepared through pressureless sinter in weakly reductive atmosphere after high energy ball milling.The electrical properties including ac conductivity, permittivity were investigated in detail.The results showed that the frequency dispersions of ac conductivity follow the power law, indicating the hoping conduction behavior.The real part of permittivity for composites increased with higher Fe content, which was attributed to the more interface between Fe and SiO2.Besides, Debye-like dielectric relaxations were observed, and the Debye-like loss peak appeared blue shift as increasing the Fe content.
