On the mechanism of exfoliation of ‘Vermiculite’ [PDF]
Clay Minerals, 2013 AbstractSix samples of ‘Vermiculite’ have been studied to investigate the mechanism of its well known but poorly understood property to exfoliate. The samples were analysed quantitatively by XRD to determine their precise mineralogical composition. Electron microprobe methods, including elemental mapping of native potassium and of caesium (introduced ...

Sheet-Size-Dependent Mosaicity of 2D Phyllosilicate Membranes. [PDF]
Adv Sci (Weinh)This study explores how the size of 2D vermiculite sheets affects the structure of laminar membranes. High‐resolution x‐ray diffraction reveals how sheet size governs structural disorder and crystallinity. These changes directly impact ion permeability.
