  • Clays and Clay Minerals, Vol. 56, No. 2, 155–174, 2008. 
    S´rodon´, Jan; Mccarty, Douglas K. (The Clay Minerals SocietyThe Clay Minerals Society, 2008)
    The total specific surface area (TSSA) and smectitic layer charge (Qs) calculated from the structural formulae and unit-cell dimensions of 12 pure smectite samples were used as a reference in the design and evaluation of ...
  • Clays and Clay Minerals, Vol. 57, No. 1, 104–114, 2009. 
    Emmerich, Katja; Wolters, Felicitas; Kahr, Guenter; Lagaly, Gerhard (The Clay Minerals Society, 2009)
    Montmorillonites, with the general composition M+ x(Si4-yAly)[(Al,Fe3+)2-z(Mg,Fe2+)z] O10(OH)2 where x = x = 0.2-0.6, x = y+z, and y<<z, vary widely in composition and structure. The commonly used classification into fivemon ...
  • Clays and Clay Minerals, Vol. 57, No. 1, 115–133, 2009. 
    Wolters, Felicitas; Lagaly, Gerhard; Kahr, Guenter; Nueesch, Rolf; Emmerich, Katja (The Clay Minerals Society, 2009)
    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 ...
  • Clays and Clay Minerals, Vol. 57, No. 3, 361–370, 2009. 
    Sucha, V.; Czimerova, A.; Bujdak, J. (The Clay Minerals Society, 2009)
    Interactions between smectite clay minerals and various organic dyes have been studied extensively, but little information has accumulated from dye interactions with mixed-layer illite-smectite (I-S) minerals, especially ...
  • Clays and Clay Minerals, Vol. 57, No. 5, 649–671, 2009. 
    Srodon, Jan; Zeelmaekers, Edwin; Derkowski, Arkadiusz (The Clay Minerals Society, 2009)
    The nature of component layers of mixed-layer illite-smectite and their possible evolution in the course of illitization have been debated since the 1960s. The present study is a new attempt to solve these problems, using ...
  • Clays and Clay Minerals, Vol. 57, No. 6, 673–685, 2009. 
    Bujnowski, Thomas J.; Guggenheim, Stephen; Brigatti, Maria Franca (The Clay Minerals Society, 2009)
    Factors controlling the crystal structure of phlogopite have been widely investigated; but the role of electrostatic interactions, for example, has received much less attention than other factors. The purpose of the present ...
  • Clays and Clay Minerals, Vol. 58, No. 1, 97–109, 2010. 
    Campos, Ana M.; Moreno, Sonia; Molina, Rafael (The Clay Minerals SocietyThe Clay Minerals Society, 2010)
    Vermiculites have the potential to serve as effective catalysts if pillared with Al, but their high charge presents an obstacle to the pillaring process. The purpose of this studywas to submit natural vermiculite to thermal ...
