| 摘 要： | 应用X射线粉末衍射技术和Rietveld全谱图拟合法分析铁矿石中所含的物相及其含量。该铁矿石主要由Fe2O3,FeOOH,SiO2,Al2(Si2O5)(OH)44种矿物组成,它们的含量分别为86.20%,9.59%,3.58%,0.64%。精修得到铁矿石各物相结构参数与已报道的数据相当接近,所测试样中铁的百分含量与化学分析法所得结果非常接近。该方法定量相分析铁矿石所获得的结果是可靠的。

| Abstract: | The weight concentration and the phases for an iron ore has been determined by using XRD technique and the Rietveld refinement method.The results show that the compositions of the iron ore are Fe2O3,FeOOH,SiO2,Al2（Si2O5）（OH）4 and their contens are 86.20%,9.59%,3.58%,0.64%,respectively.The crystal structure data of each phase obtained from the Rietveld analyses are in consistent with those previously reported in other literatures.The iron weight concentration of sample obtained from this work is close to that attained from chemical analysis.Therefore,X-ray powder diffraction technique combining with the Rietveld refinement method is reliable for measuring the percentage composition of an iron ore. |
