Hydrated Aluminium Silicate Formula
Hydrated aluminium silicate is a mineral compound commonly known as kaolinite. Its chemical formula is Al2Si2O5(OH)4, which indicates that it contains two atoms of aluminum (Al), two atoms of silicon (Si), five oxygen (O) atoms, and four hydroxyl (OH) groups.
The structure of hydrated aluminium silicate consists of layers of aluminum and silicon tetrahedra linked by shared oxygen atoms to form a sheet-like structure. The hydroxyl groups are located on the surface of these layers and interact with water molecules to form hydrogen bonds, leading to the mineral's ability to absorb moisture.
Kaolinite is a type of clay mineral that forms in soils and sedimentary rocks through the weathering of feldspar and other aluminosilicate minerals. It is widely used in industries such as ceramics, paper, paints, and plastics due to its unique properties such as high whiteness, low abrasiveness, and good plasticity.
In summary, the chemical formula of hydrated aluminium silicate, or kaolinite, is Al2Si2O5(OH)4, and it is a mineral compound composed of aluminum, silicon, oxygen, and hydroxyl groups. Its layered structure and ability to absorb moisture make it useful in various industrial applications.
