Abstract：High magnesium tundish dry material was a necessary raw material in iron and steel smelting process. The elemental content in high magnesium tundish dry material played an important role in element tracking. The experimental conditions including sample mass, dissolution method and analytical line were investigated, then a determination method of boron in high magnesium tundish dry material by inductively coupled plasma atomic emission spectrometry (ICP-AES) was established. 0.4000g of high magnesium tundish dry material sample was dissolved with potassium hydroxide followed by treatment with hydrochloric acid and nitric acid. B 182.577nm or B 249.678nm was chosen as the analytical line. In the absence of obvious interference of system, the automatic matching method (FITTED) was selected for spectral correction and background deduction. The standard solution series were prepared by matrix matching method for the drawing of calibration curve. Consequently, the determination of boron in high magnesium tundish dry material was realized by inductively coupled plasma atomic emission spectrometry. The mass fraction of boron in range of 0.0005%-0.020% (B 182.577nm) or 0.0006%-0.020% (B 249.678nm) had good linearity with correlation coefficients higher than 0.9995. The limit of detection for boron was 0.0001%. The proposed method was applied for the determination of boron in high magnesium tundish dry material samples. The relative standard deviations (RSDs, n=6) of determination results were all less than 5%. The recoveries were between 92% and 108%. The content of boron in one certified reference material of magnesia (magnesium mass fraction of 48.87%) with similar content as high magnesium tundish dry material was determined according to the experimental method. The results were consistent with the standard value.
