$Swelling behavior of Na- and Ca-montmorillonite up to 150°c by in situ x-ray diffraction experiments$

11 p, 2.1 MB

Swelling behavior of Na- and Ca-montmorillonite up to 150°c by in situ x-ray diffraction experiments / Morodome, Shoji (Tokyo Institute of Technology. Department of Earth and Planetary Sciences) ; Kawamura, Katsuyuki (Tokyo Institute of Technology. Department of Earth and Planetary Sciences)
The effects of temperature on the swelling properties of smectites are important for a variety of different geological conditions, but studies on this topic have been rather limited. The purpose of this study was to investigate the swelling behavior of Na- and Ca-montmorillonite at various temperatures greater than room temperature, up to 150°C, using in situ X-ray diffraction (XRD) analysis. [...]

The viscosity of organic liquid suspensions of trimethyldococylammonium-montmorillonite complexes / Minase, Makoto (Tokyo Institute of Technology. Department of Earth and Planetary Sciences) ; Kondo, Mitsuji (Hojun Co. Ltd. Laboratory of Applied Clay Technology) ; Onikata, Masanobu (Hojun Co. Ltd. Laboratory of Applied Clay Technology) ; Kawamura, Katsuyuki (Tokyo Institute of Technology. Department of Earth and Planetary Sciences)
An organophilic bentonite was prepared by means of a reaction of natural Na-montmorillonite with trimethyldococylammonium which has an especially long n-alkyl chain. The addition of trimethyldococylammonium to montmorillonite was in the range 0. [...]

$In situ X-ray diffraction study of the swelling of montmorillonite as affected by exchangeable cations and temperature$

11 p, 749.2 KB

In situ X-ray diffraction study of the swelling of montmorillonite as affected by exchangeable cations and temperature / Morodome, Shoji (Kunimine Industries Co. Research Laboratories) ; Kawamura, Katsuyuki (Okayama University. Graduate School of Environmental Science)
The swelling property of smectite is dominated by the hydration of exchangeable cations in the interlayer spacing ('interlayer hydration'). By investigating systematically the swelling behavior of various exchangeable cations with different valences and ionic radii, the interlayer hydration of smectite was explored. [...]
