Description | 鉄鋼スラグに含まれるアルミニウムの化学状態を分析することを目的とし,X 線分光法を用いて,Al Kα線のケミカルシフトと配位数との相関からスラグ中に含まれるアルミニウムの化学状態分析を行った.スラグ試料としては,アルニミウムを約14 ~ 31[mass%] 含む高炉スラグ及び製鋼スラグを用いた.また,実際にスラグ試料を測定する前に,配位数の既知であるアルミニウム化合物について蛍光X線分光法により,配位数とケミカルシフトとの相関を確認した.これらの結果,本研究で用いたスラグ試料に含まれるアルミニウムはいずれも4 配位型(AlO4 型)の構造であることが結論された.

Description Alternative | In order to analyze chemical state of aluminum in iron and steel slag, aluminum contained in slag is analyzed by X-ray spectrometry after the measurement of correlation between chemical shift of Al Kα lines and effective charges. We use blast furnace slag and steelmaking slag including approximately from 14 to 31 mass percent of aluminum as slag samples. Aluminum compounds, whose coordination numbers are known, are investigated with correlation between coordination number and chemical shift by X-ray fluorescence spectrometry before the measurement of slag samples. As a result of this study it can be concluded that aluminum contained in each of slag samples are 4-coordinated.
