摘要: 用正硅酸乙酯(TEOS)对羰基铁颗粒进行表面改性,用扫描电镜、矢量网络分析仪等,对羰基铁在2—18 GHz范围内改性效果和影响规律进行了研究。结果表明,包覆SiO₂降低了羰基铁介电常数实部,但对磁导率实部影响较小;羰基铁的电磁匹配性能得到改善。

Abstract: The surface of carbonyl iron particles was modified using TEOS, the carbonyl iron modification effect within 2-18GHz and the influence rule were analyzed by the scanning electron microscopy (SEM), the vector network analyzer. The results show that coated SiO₂ reduces the real component of carbonyl iron dielectric constant, but the real component magnetic permeability changes a little. The electromagnetic matching performance of carbonyl iron is improved.
