The Montmorillonite seems to be just a bunch of pink smudges in the crystal, but closer examination reveals that the smudges are made up of fibrous sprays of "crystals", or what appear to be. The third face of the quartz seems to be fogged over with milky quartz, which is concentrated uniformly along the same plane as the Montmorillonite.
Clay mineral is an important material available in nature.

Montmorillonite did not demonstrate similar properties during similar treatment; the water-vapor adsorption activity remained at the level of the untreated material. The specific surface area of the kaolinite increased fourfold. Moreover, the results are satisfactorily reproduced with the use of kaolinite from two different deposits, which ...

Montmorillonite refers to a family of non-metallic clays primarily composed of hydrated sodium calcium aluminum silicate. It takes extra strong adsorption capacity and can absorb 8-15 times …
montmorillonite is to treat it as two planar negatively charged surfaces neutralized by sodium and/or calcium counterions-see Figure 1. The lamellar structure is assumed to be in equilibrium
Montmorillonite is a phyllosilicate mineral clay of smectite gourp. There are three types of Montmorillonite clays with reddish, bluish, and greenish tints. Blue montmorillonite clay has the same benefits as Red Montmorillonite but is bluish-gray in color. It is a powerful absorbent, more so than French Green.
Montmorillonite (Grim 1968) has a layer structure with 2:1 arrangement: Each layer is composed of three sheets.Two outside sheets, called tetrahedral sheets, contain silicon ions, Si 4+, tetrahedrally coordinated to oxygens.The middle sheet, called the octahedral sheet, is made up of aluminum ions, Al 3+, surrounded by oxygens in octahedral coordination.
This study investigates the rheological properties of two parallel Na-montmorillonite particles. An Arizona-type montmorillonite model with a unit cell formula of Na 0.75 + Si 8 (Al 3.25 Mg 0.75) O 20 (OH) 4 was utilized, which was constructed based on a pyrophyllite unit cell structure obtained through single-crystal X-ray refinement (Lee and Guggenheim, 1981).
for the montmorillonite/illite system, without being so simple that it has no relation to nature. The iron con tent ofthe mixed-layer minerals ofHower and Mowatt (1966) is fairly constant, as is the magnesium content. The important differences between montmorillonite and illite involve K 20, A120 3, Si02, and H 0. THEORETICAL MONTMORILLONITE
