在 X 射线衍射定性分析的基础上，结合 Rietveld 全谱拟合方法对不同龄期磷酸镁水泥样品的水化产物晶相含量进行了定量研究。结果表明，龄期为10 min、1 h 及1 d 的磷酸镁水泥样品中水化产物 MgKPO4·6H2 O 的相对含量分别为12.39%、15.77%和18.38%，拟合的 Rwp因子为9.73%~12.8%，说明该方法能准确、直观、快速的确定不同龄期样品中各晶相的组成及相对含量，并获得各相的相关晶体学结构参数，同时结合相关理论对磷酸镁水泥的水化及性能作出客观分析，为加深对水泥材料的认识提供了一种可行的研究方法。

Based on the qualitative analysis of X-ray diffraction,combined with the rietveld whole pattern fitting method,the quantitative research for content of hydration products crystalline phase in magnesium phosphate cement at different hydration time was achieved. Results showed that the relative content of hydration products MgKPO4 ·6H2 O in magnesium phosphate cement at hydration time 10 min,1 h and 1 d were 12. 39% ,15. 77% and 18. 38% ,respectively. The Rwp factor changed from 9. 73% to 12. 8% ,which indicated that the method could confirm the crystalline phase composition and relative content in magnesium phosphate cement accurately,intuitively and rapidly. It could obtain the crystallography parameters of every crystalline phase. Also in combination with the related theory,the hydration and performance of magnesium phosphate cement could be analysised objectively,thus provided a feasible method to deepen the understanding of cement materials.
