泡状Fe3O4粉体的制备及其微波吸波性能
Research on Synthesis and Electromagnetic Absorption Properties of Porous Fe3 O4 Powders
摘要
Abstract
This paper,taking FeCl3 ·6 H2 O and CH3 COONa as source materials,prepares Fe3 O4 powders by hydrothermal method to compare the superior of absorption with solid Fe3 O4 powders.The paper analy-zes the crystal structure of Fe3 O4 powders by X�ray diffraction (XRD),and the size and the morphology of the prepared products by scanning electron microscopy (SEM)and transmission electron microscopy (TEM).The paper tests the electromagnetic parameters of coaxial samples by network analyzer to obtain the microwave absorption of porous Fe3 O4 powders.The results indicate that the density of porous Fe3 O4 powders is lower than that of the solid Fe3 O4 powders,and the real part of permittivity of porous Fe3 O4 powders is absolutely higher.When the thickness of samples is thicker than 4 mm,the absorption of pre-pared porous Fe3 O4 powders is definitely superior.关键词
