Improvement of fusion sample preparation technology for refractory analysis by X-ray fluorescence spectroscopy

对于采用X射线荧光光谱法分析耐火材料时,熔融制样过程中存在高铝质和含碳化硅耐火材料气泡难以消除、腐蚀铂金坩埚的问题进行了分析和试验。通过试验得出助熔剂的选择及其加入方法是解决上述问题的关键,并找到了最佳解决方法。通过该方法的准确度和稳定性试验得出该试验方法的最大绝对误差为0.04,最大标准偏差为0.0687,同时与传统化学方法进行了比较,确定数据可靠准确。

During fusion sample preparation of high-aluminum and SiC-containing refractories for X-ray fluorescence spectroscopy,problems such as bubbles and corrosion to platinum crucibles are hard to eliminate.In the paper,analysis and experiments are conducted to deal with these problems.The experiments show that the selection of flux and the dosing method are the keys to solving the above problems,and have revealed the best solution.With this solution,the accuracy and stability experiments show a maximum absolute error of 0.04,and a maximum standard deviation of 0.0687.In addition,the data are proven reliable and accurate by comparing with the traditional chemical method.
