Effect of Water Immersion on Raw and Expanded Ugandan Vermiculite [PDF]
Minerals, 2021 Effect of water immersion at different times (from 1/2 h to 24 h) on raw and expanded vermiculite from Uganda was investigated. The expansion was carried out by electrical heating at different temperatures and by irradiation with microwaves. After, the expansibility (k) and the water absorption content (WA) were obtained and the samples were ...

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.
