摘要：

用X射线衍射 (XRD) 法对赛隆刚玉砖中的矿物相进行了定量分析，指出合成赛隆相的分子式为Si3Al3O3N5，并借助于扫描电镜（SEM）和能谱仪(EDS)，观察了赛隆相的晶体及发育形貌等显微结构。结果表明：通过X射线衍射方法定量分析赛隆刚玉砖中赛隆、刚玉、碳化硅等矿物相的含量，与欧洲DIFK实验室分析的矿物相结果一致，完全满足要求，说明了X射线衍射方法可用于赛隆刚玉砖中的矿物相定量分析。

Abstract:

This paper introduces the quantitative analysis of mineral phase in Sialon-bonded corundum brick by X-ray diffraction (XRD) method,and points out that the molecular formula of Sialon-bonded phase is Si3Al3O3N5,and obverses the crystal and morphology of Sialon-bonded phase with scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS).The results show that the contents of mineral phases in Sialon-bonded phase,silicon carbide and corundum phases in Sialon-bonded corundum brick is quantitatively analyzed by X-ray diffraction method,which are consistent with the results of DIFK laboratory in Europe and completely meet the requirements,indicating that X-ray diffraction method can be used for quantitative analysis of mineral phases in Sialon-bonded corundum brick.

Key words: Sialon-bonded phase, X-ray diffraction, Quantitative analysis
