...The hydration properties of 2:1-clay minerals are controlled to a large extent by the interlayer cations (for instance, see Hendricks et al., 1940; Mooney et al., 1952; Suquet et al., 1975; Bergaya et al., 2006)....

...…investigated because of their remarkable physical and chemical properties: low thermal conductivity and density, refractory behaviour, and high cation exchange capacity, properties that lead to various industrial applications (Strand and Stewart, 1983; Hindman, 1992; Bergaya et al., 2006)....

...…their layer charge, of disorder effects, and of their ability for dehydration–rehydration and the associated swelling processes (Mathieson and Walker, 1954; Shirozu and Bailey, 1966; Grim, 1968; Brown and Brindley, 1980; de la Calle and Suquet, 1988; de la Calle et al., 1988; Bergaya et al., 2006)....

...They present a wide variety of physical–chemical properties as a result of their lamellar structure, of their layer charge, of disorder effects, and of their ability for dehydration–rehydration and the associated swelling processes (Mathieson and Walker, 1954; Shirozu and Bailey, 1966; Grim, 1968; Brown and Brindley, 1980; de la Calle and Suquet, 1988; de la Calle et al., 1988; Bergaya et al., 2006)....

...On the other way, it is known that: a) Structural Fe and Fe both significantly impact the smectite–water interaction (Stucki, 1988); b) The swellability of sheet-silicates as vermiculite is affected by the cationic composition of the interlayer space (Mathieson and Walker, 1954; Shirozu and Bailey, 1966; Grim, 1968; Brown and Brindley, 1980; de la Calle and Suquet, 1988); and c) the presence of reduced structural iron has a depressing effect on water retention capacity in smectites (Yan and Stucki, 1999, 2000)....
