The properties of the betonie are analyzed by rock and mineral analysis, XRD, SEM, particle size analysis, chemical composition analysis, and so on. The bentonite is a calcium-montmorillonite and it is a type of 2-octahedrons' body. And it has cheto characteristics. The bentonite contains more impurities. The study lay the foundation for the development and utilization of Huludao bentonite.%本文通过岩矿鉴定、XRD、扫描电镜、粒度、化学成分等分析,对葫芦岛膨润土的性能进行了分析研究,该膨润土属于钙基、二八面体蒙脱石,结晶度较好,并具切脱型蒙脱石的特点,膨润土中含较多杂质.本研究为该膨润土的开发利用奠定了基础.
