摘要
采用XRF、XRD、BET、SEM、TEM、EDS等对榆林原矿高岭土的组成、结构、形貌等进行检测分析,以期对后续资源综合利用提供依据。实验结果表明,高岭土是一种以高岭石为主要成分的黏土矿物,原矿高岭土具有高岭石的结构,是由片状、蠕虫状以及叠片状组成。其成分复杂,主要成分为Al2O3和SiO_2,此外,还含有少量的Fe2O3、TiO_2及未燃烬的物质等其它成分。原矿高岭土的比表面积为18.4431 m2/g,且孔径分布范围较广,大孔居多,平均孔径在60～80 nm。
The composition, structure and morphology of the ore kaolin from Yulin were analyzed by XRF, XRD, BET, SEM, TEM and EDS techniques in this work to provide the basis for the comprehensive comprehensive utilization ofsubsequent resources. The experimental results showed that the structure of the ore kaolin is kaolinite, consisted of flake, vermicular and folding sheet, and has the complicated composition, the main composition is Al2O3, SiO2, a small amount of Fe2O3, TiO2 and other non-combustion ingredients. Furthermore, the ore kaolin has a certain surface area of 18. 4431 m2/g, and the pore size distribution range is wide, majority is the big hole, and the average pore size in 60-80nm.
