Abstract |
Positronium (Ps) annihilation spectroscopy and thermogravimetry and differential thermal analysis
(TG-DTA) were conducted for synthetic smectite clay minerals to investigate local molecular structures induced
by water adsorption and desorption. The TG curves indicate the weight loss of ~ 3.5 wt %, ~ 2.5 wt %,
and ~ 2.0 wt % for saponite, hectorite, and stevensite due to dehydration, in accordance with DTA endothermic
peaks around 332 K, 350 K, and 345 K. It is found based on the results of Ps lifetime spectroscopy
that the presence of angstrom-scale open space is sensitively dependent on water adsorption and desorption
in smectite clay minerals.
