    Carstea, Dumitru Dumitru
    Abstract:
    The influence of pH (titration method) and of salt concentration and drying (drying method) upon the formation of synthetic AI, Fe, and Mg interlayers in montmorillonite and vermiculite was investigated. Interlayer formation was evaluated by X-ray diffraction measurements of basal spacings using a natural chlorite for comparison. The titration method...

  • Formation and stability of Al, Fe, and Mg interlayers in montmorillonite and vermiculite

    Creator:
    Carstea, Dumitru Dumitru
    Abstract:
    The effects of pH and time on the formation of hydroxy-Al, Fe, and Mg interlayer were compared for montmorillonite and vermiculite. The stability of interlayers was evaluated by sequentially increasing the severity of dissolution treatments and by subjecting the inter-layers to an HC1 treatment. The interlayer formation and stability were...
