摘　　要：报道了一种精铁矿粉中微量二氧化硅含量测定的新方法,重点探讨了操作中各步骤的最佳工艺及其对硅含量分析精确度的影响。本方法分析精确度高,适合于精铁矿粉中微量二氧化硅含量(SiO2:0.01%～1%)的测定,比传统方法测定极限下延了10倍。A new method of determination of trace silica in refined iron ore powder is reported in this paper, which the optimum condition in operation and its effects on the accuracy of the content are discussed. It indicated that this new method is accurate and fit for determination of trace silica(SiO_20.01%～1%)in refined iron ore powder, and its detection limit is drawn as 10 times wide as the traditional methods.
