文摘

Industrial grade bentonite clay and its corresponding metabentonite structures were studied. The extended and local range order structure characterization was carried out by two X-ray based techniques: XRD and XANES. Local Aluminum and Silicon environments were described and characterized by this synchrotron based techniques.
