桂西堆积型铝土矿中三水铝石定量分析方法对比研究

Study on Quantitative Analysis Method for Gibbsite in Accumulatied Type of Bauxite from Western Guangxi Province

摘要: 采用X衍射标样增量法对红土中三水铝石进行了定量分析，并将该方法分析结果与化学物相分析结果进行了对比。结果表明，利用X衍射标样增量法测定红土中的三水铝石含量，获得的结果可靠，5份样品重复测定的RSD为2．8％，是桂西堆积型铝土矿区红土中三水铝石较为理想的定量分析方法。

Abstract: X-ray diffraction with standard increment method has been developed for quantitative analysis of gibbsite in accumulated type of bauxite. The results have been compared with those from chemical phase analysis with satisfaction. The results show that X-ray
