摘要
本文应用了红外光谱、X-射线衍射等现代分析测试手段对广丰膨润土矿的矿物组成及其特征进行了系统分析。结果表明:广丰膨润土以蒙脱石为其主要矿物成份,具两层层间结晶水结构,热稳定性能良好;地下深部以钠基蒙脱石为主,近地表逐渐以钙基蒙脱石为主。
Systematic studies on the mineral compositions and characters of the bentonite from Guangfeng were conducted by means of chemical analysis、XRD、SEM、IR and DTA-TG. The results showed that the principal mineral composition was Na-montmorillonite in the deep-seated layer and Ca-montmorillonite in the surface layer. Both Na- and Ca-montmorillonite were dominated by two interlaminar crystal water structure.
