摘　　要：研究了2-18GHz微波频率范围内印度、南非和中国松树沟三种铬铁矿粉的电磁特性，分析了铬铁矿粉的几个重要电磁参数随频率变化曲线，认为印度铬铁矿粉的电磁特性较优于南非和中国松树沟的铬铁矿粉，其原因是印度铬铁矿粉Cr＊（Cr＊=Cr／（Cr＋Al））、Cr^3＋、Cr2O3及杂质含量较高。In this article there are studied the electromagnetic characteristics of three kinds of chromite ore fines produced in India, South Africa, and Songshugou of China at microwave frequency between 2 and 18GHz. From the analysis of the dependence of several electromagnetic parameters for chromite ore frees on frequency, it can be concluded that the electromagnetic characteristics of Indian chromite ore fines are better than those of South Africa and China, which is due to its higher contents of Cr＊ [ Cr＊ = Cr/（Cr ＋ Al） ], Cr^3＋ ,Cr2O3 and impurity.
