What is sodium montmorillonite?

Sodium montmorillonite is a naturally occurring clay and hence its properties and composition can vary. It falls into the smectite group and is largely used for its swelling and adsorption properties. K10 is an acid treated clay.

What is clay’s chemical formula?

Kaolinite is a clay mineral of chemical formula Al2O3 2SiO2·2H2O that has a structure of 1:1 uncharged dioctahedral layer where each layer consists of single silica tetrahedral sheet and single alumina octahedral sheet [123,124].

What is the chemical formula for kaolinite?

Kaolinite (/ˈkeɪ.ələnaɪt/ KAY-ə-lə-nyte) is a clay mineral, with the chemical composition Al2Si2O5(OH)4. It is an important industrial mineral. It is a layered silicate mineral, with one tetrahedral sheet of silica ( SiO 4) linked through oxygen atoms to one octahedral sheet of alumina ( AlO 6) octahedra.

What is the formula of Gibbsite?

Gibbsite is an aluminum hydroxide mineral of the oxides and hydroxides group, with structural formula [Al(OH)3]. Gibbsite’s structure is made up by the stacking of octahedral sheets of aluminum hydroxide.

How is montmorillonite used?

The important functional utilization of montmorillonite includes food additive for health and stamina, for antibacterial activity against tooth and gum decay, as sorbent for nonionic, anionic, and cationic dyes, and the use as catalyst in organic synthesis.

How is kaolinite used?

Kaolinite is important to the production of ceramics and porcelain. It is also used as a filler for paint, rubber and plastics since it is relatively inert and is long lasting. But the greatest demand for kaolinite is in the paper industry to produce a glossy paper such as is used in most magazines.

How stable is a montmorillonite clay particle?

Thus, a montmorillonite clay particle is stable as long as it is dry but breaks into individual struc­tural units in the presence of water. The chemical formula of montmorillonite is (Na, Ca) 0. 33 (Al, Mg) 2 Si 4 O 10 (OH) 2 .n (H 2 O) and its molecular weight is 549.07 g.

What are the common uses of sodium montmorillonite?

Sodium montmorillonite is commonly known as sodium bentonite. volume. ment tiles, lubricating grease, dynamite, matches, paints, copy paper, shoe polish, concrete, cleaning agents, wall boards, and crayons. Most of these uses are attributed to swelling property of sodium montmorillonite.

What is the charge on montmorillonite?

For montmorillonite, the total negative charge contributed to the structure by the sum of all the oxide anions (O 2 -) is somewhat in excess of the total positive charge contributed by the sum of all the structural cations (Si+4, Al+3, Fe+2, Fe+3, Mg+2) and imparts a slight overall negative charge to the surfaces of the clay sheets.
