摘要
以白云鄂博选铁尾矿为原料制备吸波材料,在7.6～11.5GHz对其吸收特性进行分析研究,实验结果表明,在富含铁及多种稀土元素的选铁尾矿中加入2%的磁性及电性介质,经过650℃热处理后,最大吸收量达21dB,13dB带宽2.4GHz。该尾矿用于制备吸波材料,具有较大的研究意义。
In this paper,the properties of absorption materials which were made by using the tailings from iron ore dressing in Baiyunebo were studied in the frequency of 7.6~11.5GHz.If we add electric or magnetic media to the tailings from iron dressing which contain abounding iron and many rare earth elements and then heattreat at 650℃. we found that the absorption quantity and 13dB bandwidth of it will increase to 21dB and 2.4GHz respectively.So it is very significant to the making of absorption material by tailing from iron.
