    The samples acidtreated for 5 h show high swelling capacities, around 16 mL/g, after 24 h of the high shear homogenization process, that is, approximately 11 times larger than the swelling of the untreated vermiculite (Fig 5a) These swelling capacities correspond to substantial increases in the osmotic swelling and may be related to the partial dissolution of the octahedral sheets of the vermiculite

  • Continuous energy efficient exfoliation of vermiculite

    Vermiculite has a low thermal capacity due to its high surface reflectivity which means it is highly effective at reflecting incident thermal radiation (Andronova, 2007), and therefore requires a significant amount of energy for its exfoliation (often greater than 1 Mwh/t of material) This is one of the many limitations of current industrial processing methodologies based on either rotary or vertical
