Talc is also a tri-octahedral 2:1 layer silicate mineral, characterized by three octahedral Mg positions per four tetrahedral Si positions (7), (8).
In this regard, discussion of the surface and colloid chemistry of the two layer silicate minerals seems to be an appropriate contribution to this special volume of The Canadian Journal of Chemical Engineering in recognition of Jacob Masliyah and in celebration of his 65th birthday.
The surface chemistry and, in particular, the electrokinetic characteristics of two layer silicate minerals, specifically kaolinite, has received considerable attention with regard to the influence of crystal structure anisotropy on the behaviour of particulate suspensions.
The faces of a planar two layer silicate (kaolinite or antigorite) particle would not have an anisotropic "heads and tails" characteristic with one face consisting exclusively of silica tetrahedra and the other face consisting of alumina or magnesia octahedra.
You will also often use the term clay to refer to a class of soil minerals, namely the layer silicate clays.
Layer silicate clay minerals also have important chemical properties.
The most common in most soils are the layer silicate clays.
The Part II of this study covers the preparation of untreated layer silicate NC by dispersing the clay in the aqueous phase (15).
In general, the layer silicate is modified with alkylammonium, which is hydrophilic and this facilitates its interaction with the polymer.
The presence of sizeable amounts of gibbsite in the sand fractions amidst layer silicates suggests that the genesis of gibbsite in the presence of layer silicates is highly possible.
Formation of hydroxy-interlayered layer silicates and gibbsite
