Clay Fabrics Clay Minerals Microdrilling Micromorphology Transmission X-ray Diffraction Undisturbed Microsamples
2011/12/7
Abstract: Clay mineralogical studies by X-ray diffraction performed on extracted <2-祄 fractions do not always represent all clay mineral constituents present in the soil. In this work, transmission X-...
Characterization of the Solids Obtained by Pillaring of Griffithite (High Iron Content Saponite) with Al-Oligomers
Al13-Keggin Polycation Griffithite Iron-Saponite Pillaring Porosity Saponite
2011/12/22
Abstract: Griffithite, a high Fe content saponite (Griffith Park, California) was pillared with Al polymeric solutions, using different Al/clay ratios. The cation exchange began when Al-polycation sol...
