硅铁中硅含量测定对铁合金生产具有重要指导意义.本文采用样品粉末压片法,探讨和概述了使用X射线荧光光谱法测定硅铁中硅含量的方法. 精密度和准确性实验以及长期稳定性考察表明,相比化学法误差小,分析速度快,重复性好,能够很好的在日常生产中应用.“,”the determination of silicon content in ferrosilicon alloy production has important guiding significance. In this paper, using the sample powder tabletting method, this paper discusses and summarizes the use of X-ray fluorescence spectrometry method of silicon content in ferrosilicon. Precision and accuracy of the experiment and the long-term stability test showed that compared with the chemical method of error is small, fast analysis speed, good repeatability, can very good application in daily production.
