Institute for Functional Interfaces) ; Emmerich, Katja (Karlsruhe Institute of Technology. Institute for Functional Interfaces)
The industrial assessment of ceramic clays commonly consists of the determination of just two parameters, the particle-size distribution and the chemical composition; other parameters may also be important, however. [...]

11 p, 161.0 KB Clay profiling : The classification of montmorillonites / Emmerich, Katja (Forschungszentrum Karlsruhe. Competence Center for Material Moisture. University of Karlsruhe) ; Wolters, Felicitas ; Kahr, Guenter (ETH Zürich. Institute of Geotechnical Engineering) ; Lagaly, Gerhard (University of Kiel. Institute of Inorganic Chemistry)
Montmorillonites, with the general composition M (SiAl) [(Al,Fe) (Mg,Fe)] O(OH) where x = ξ = 0. 2a0. 6, x = y+z, and y«z, vary widely in composition and structure. The commonly used classification into five montmorilloniteand two beidellitegroups for the solid-solution sequence does not allow an unambiguous classification with respect to structural features and the resulting properties. [...]

19 p, 542.5 KB A comprehensive characterization of dioctahedral smectites / Wolters, Felicitas (Forschungszentrum Karlsruhe GmbH. Institute for Technical Chemistry) ; Lagaly, Gerhard (University of Kiel. Institute of Inorganic Chemistry) ; Kahr, Guenter (ETH Zürich. Institute for Geotechnical Engineering) ; Nueesch, Rolf ; Emmerich, Katja (University of Karlsruhe. Competence Center for Material Moisture)
The term 'montmorillonite' encompasses a wide range of chemical compositions and structures. Comprehensive and reliable characterization is essential for unambiguous classification. Twenty eight purified, Na-exchanged smectites (<0. [...]

8 p, 335.5 KB Cation exchange reactions of vermiculite with Cu-triethylenetetramine as affected by mechanical and chemical pretreatment / Steudel, Annette (Forschungszentrum Karlsruhe GmbH. Institute of Functional Interfaces) ; Weidler, Peter G. (Forschungszentrum Karlsruhe GmbH. Institute of Functional Interfaces) ; Schuhmann, Rainer (Forschungszentrum Karlsruhe GmbH. Institute of Functional Interfaces) ; Emmerich, Katja (Forschungszentrum Karlsruhe GmbH. Institute of Functional Interfaces)
The cation exchange capacity (CEC) is a characteristic property of expandable clay minerals, such as smectites and vermiculites. The aim of this work was to examine the cation exchange behavior of vermiculite using the Cu-triethylenetetramine (Cu-trien) CEC method and the influence of mechanical and chemical pretreatment, with the ammonium acetate method serving as a reference. [...]
