In this thesis, the several methods to prepare nano-magnetoplumbite compoundoxide-BaCo_2Fe_(16)O_(27) -were studied and the advantages and disadvantages ofdifferent methods were compared.
本文深入地研究了制备纳米磁铅石型复合氧化物-BaCo_2Fe_(16)O_(27)粉体的几种方法,比较了不同合成方法的优缺点,并通过测定与分析得出:柠檬酸溶胶-凝胶法是合成该复合氧化物的比较适宜的方法。
The results show that no strontium ferrite with a magnetoplumbite structure is crystallized when the precursor have been decomposed at 450 ℃.
采用柠蒙酸法合成具有热稳定性的SrFe1 2 O1 9磁铅石型铁氧体。
The concentration of ferrum,barium and lanthanum elements in magnetoplumbite doped rare earth ferrites was directly determined by X-ray fluorescence spectrometry with the pressed powder samples.
采用X射线荧光光谱分析方法,直接粉末压片测定磁铅石型稀土铁氧体中Fe、Ba、La等元素的浓度,实验结果表明:在最佳仪器工作条件下,测试结果的相对标准偏差均<1。
