chemical composition of clay

  • 2. The composition of clay materials Geological

    Clay materials are composed of solid, liquid and vapour phases. The solid phases are of mineral and organic phases that make up the framework of the clay materials. The mineralogy can be broadly subdivided into the clay and non-clay minerals, including poorly crystalline, so-called ‘amorphous’ inorganic phases. By definition, minerals are crystalline solids with well-ordered crystal

    1998-5-13 · Clay minerals are very small, usually less than 4 µm in diameter, and have net negative sur-face charge (Brindley and Brown, 1980). Their high surface area and negative charge, providing large reaction surface and ion-exchange capacity, allow clay minerals to track relatively subtle changes in flu-id chemical composition.
