摘要
对采自江苏盱眙的坡缕石进行了化学成分分析、扫描电镜、X射线衍射、差热和红外光谱的研究。结果表明研究区的坡缕石属沉积型的土状坡缕石,结构特征为单斜晶系,其结晶程度一般。
According to the results of chemical composition,scanning electron microscope,X-ray powder diffraction,infrared spectra and thermogravimetry analysis,the mineralogical characteristics of palygorskite from Xuyi,Jiangsu province are studied in this paper. It shows that the crystal shapes assume fibrous, acicular and rod forms,and the aggregates vary greatly in shape. This kind of palygorskite belongs to monoclinic system. Its ordering degree is lower. Its morphological and physical features are somewhat different from the features of hydrothermal palygorskite from Quanjiao, Anhui province.
