由于技术和设备的原因,矿物高温 X 射线衍射研究,一直是矿物研究中的薄弱环节。笔者采用日本 D/MAX RA 型高温 X 射线衍射仪,对苏南江宁县淳化地区的蒙脱石粘土(膨润土)进行了系统实验,为扩大蒙脱石粘土的工业利用范围,提供了新的资料。一、样品和实验条件(一)样品样品取自淳化蒙脱石粘土矿区的商品土。经 X 射线衍射定性分析,主要矿物组分为:蒙脱石(>85%),并含有少量的蛋白石、长石、水云母以及石英(图1)。
Due to technical and equipment reasons, high temperature X-ray diffraction studies of minerals have been the weak link in mineral research. The author used Japanese D / MAX RA high temperature X-ray diffractometer to conduct a systematic experiment on montmorillonite clay (bentonite) in Chunhua area, Jiangning County, southern Jiangsu Province, and provided a new method for expanding the industrial utilization range of montmorillonite clay data. First, the sample and experimental conditions (a) Sample samples were taken from Chunhua montmorillonite clay mining area of commercial soil. Qualitative analysis by X-ray diffraction, the main mineral components: montmorillonite (> 85%), and contains a small amount of opal, feldspar, aqua mica and quartz (Figure 1).
