摘 要: 采用內標法、絕熱法、全譜擬合法三種方法對MgO-Al2O3二元體系的一系列已知物相組成的樣品進行X射線衍射(X-ray diffraction,XRD)定量分析研究。結果表明,三種定量分析方法的分析結果均與實際組成較為吻合,分析精度在±5%范圍內,未表現出明顯差異。絕熱法由于定量分析程序簡單、效率較高,更適宜于工業生產中MgO-Al2O3二元體系的物相組成快速定量分析。

Abstract: A series of samples of the known phase composition in MgO-Al2O3 binary system was quantitatively analyzed with X-ray diffraction (XRD) by the internal standard method, the reference intensity ratio (RIR) method and the Rietveld method. The results showed that the phase content obtained by each method was in consistent with the actual composition, and the measurement error was ±5% with no obvious significance. However, the RIR method was more suitable for the rapid quantitative analysis of the phase compositions of MgO-Al2O3 binary system in industrial production due to its simple program and high efficiency.
