Chemical Formula For Clay

Thus clay consists of aluminium oxide Al 2 O 3 silicon dioxide SiO 2 and iron iii oxide Fe 2 O 3 along with water molecules. This particular clay is a soft gray color but does not necessarily represent all of the Wyoming bentonites.

Some clay minerals may be expressed using ideal chemical formulas as the following. SiO 2 533-612 Al 2 O 3 243-325 Fe 2 O 3 12-17 TiO 2 1-11 CaO 02-03 MgO 02-04 K 2 O 03-13 Na 2 O 01-03 PHYSICAL PROPERTIES. It is formed by the decomposition of some part of feldspar mineral.

Clay is hydrated aluminium silicate and iron iii oxide having chemical formula Al 2 O 3 SiO 2 Fe 2 O 32H 2 O. Clay is an alumina silicate with the formula Al2O3 2SiO2 2H2O but it is usually not found in pure form in nature. Primary clay formed by natural kaolinisation process.

The SiO 2 ratio in a formula is the key factor determining clay. Illite is a high-charge TOT clay mineral in which sheets are bound relatively strongly by more numerous potassium ions and so it is not a swelling clay and has few industrial uses. There are many different clay minerals.

Clay Mineralogy 2nd edition McGraw-Hill Book Company New York 1968 41. Na02Ca01Al2Si4O10OH2H2O10 Sodium bentonite is the name for the ore whose major constituent is the clay mineral sodium montmorillonite. It is a 11 clay mineral the basic unit is composed of a 2-dimensional 2D layer of silicate groups tightly bonded to a 2D layer of aluminate.

The repeat unit is a single silicate sheet condensed with alumina octahedra. 2SiO 22H 2 O. Kaolinite is the most common clay mineral and entire clay deposits can be composed of this mineral.

The Kaolinite Groupconsists of polymorphs of formula Al2Si2O5OH4. Alkali and organic matter -1. 2SiO 2 Al 2 O 3 2H 2 O kaolinite 4SiO 2 Al 2 O 3 H 2 O pyrophyllite 4SiO 2 3MgOH 2 O and 3SiO 2 Al 2 O 3 5FeO4H 2 O.

Also known as potash bentonite or K-bentonite potassium bentonite is a potassium-rich illitic clay formed from alteration of smectic clay. Silica is present in brick clay as the chemical composition of alumina and forming silicate of aluminaSometimes silica is present in pure form termed as flint. 07032011 The chemical composition of brick clay is as follows-.

MINERALOGY AND CHEMICAL COMPOSITION OF CLAY MINERALS 279 Fe2O3 differences in total Fe as Fe 2O3 incorporated into clay matri-ces may indicate changes in chemical environment of formation.

The chemical formula of China clay is Al2Si2O5OH4. Clay particles in soil result from the physical and chemical weathering of silicate-containing rock. Kaolinite is the principal mineral in kaolin clays.

KAlSi8AlOOHusuallywith 1y y4-yy204 15butalwayswithy2. Clay minerals have a sheet-like structure and are composed of mainly tetrahedrally arranged silicate and octahedrally arranged aluminate groups. There are many commercial Kaolinite mines where this mineral is mined in large volumes for its various industrial uses.

Ball clay should never tested for colour in the concentrated state since its density and adsorbed salts give colour intensities which are misleading.
