Benefits, Uses and More Power Food Health2021年9月30日 While we often focus on the two ‘end members’ of clay mineral activity (kaolinite and smectite), we classified the various maps into active clays (smectite and vermiculite), moderately active clays (illite, goethite, gibbsite, and chlorite), and inactive clays (kaolinite) based on observed presence of interlayer structure for each respective mineral, reflected by Clays Are Not Created Equal: How Clay Mineral Type Affects Soil 2022年1月1日 According to the structures characteristic of kaolinite and clay minerals of the smectite group, the reactions of delamination and exfoliation occur easily in the intercalated compounds (Fig 110), but in kaolinite only after intercalation with some key organic molecules (Fig 111), due to the hydrogen bonds that hold the layers together (EqClay minerals: Classification, structure, and properties
