摘要
通过化学分析、岩矿鉴定、红外光谱、热重-差热分析、X射线衍射和扫描电镜分析测试和观察,对江西萍乡某矿煤系硬质高岭土的矿物学特征进行了研究。结果表明:江西萍乡煤系硬质高岭土矿物组成简单,主要由高岭石组成,杂质含量极少,结晶程度高,可用于合成催化剂用分子筛和制备有机物插层等。在此基础上,进行了高岭石-甲酰胺插层复合物制备的试制研究。
This paper studied the mineralogy characteristics of coal series hard kaolin of Pingxiang by means of chemical analysis, mineral examination, infrared spectrum, thremogravimetric -differential thermal analysis, X- ray diffraction, scanning electron microscopic analysis. The results showed that the hard kaolin was made up of kaolinite mainly with tiny impurities, and its crystallinity was good, which can be used as the materials for preparation of catalyzer - carrier molecular sieve and intercalation compound. Based on the results, the authors have made the research of kaolinite- formamide ntercalation compound.
