Caolinita

1:1 Clay Mineral Structures: Kaolinite and its relatives Recall that each layer of the 1:1 minerals is made from one tetrahedral sheet linked to one octahedral sheet. The octahedral sheet can be either dioctahedral or trioctahedral, which splits the 1:1 clay minerals into two subgroups.

Illite Mineral Data

Kaolinite. The most fundamental clay mineral. This mineral is found in nature in its purest form as kaolin. However it makes up at least part of all ceramic clays. The purest deposits are created as it is weathered from rock and deposited, mixed with other products of the weathering process, in layers and lenses in nearby valleys.

Kaolinite

Kaolin is not only a raw material for one of the finest products, porcelain, but also a type mineral for a varied spectrum of environments of deposition characterized by a rather sharp upper limit of formation of 390 ± 10 °C at a pressure of 2000 bar.

Kaolin – Sibelco

Kaolinite, which is named for its type locality, Kao-Ling, Jianxi, China; is a common phyllosilicate mineral. It lends it name to the Kaolinite Group, members of which also belong to the larger general group known as the Clays. Kaolinite's structure is composed of silicate sheets (Si 2 O 5) bonded to aluminum oxide/hydroxide layers (Al 2 (OH) 4) called gibbsite layers.

Clay mineral

Clay minerals are hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces.. Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them. They are important constituents of soils, and have been useful to humans ...

Kaolinite Mineral Data

Kaolinite. Kaolinite is a common 1:1 dioctahedral phyllosilicate (clay) mineral found in soils across the world, particularly in highly-weathered environments, as well as scattered monomineralic deposits that are mined for industry. Being a 1:1 mineral, each kaolinite layer has one silica tetrahedral sheet and one alumina octahedral sheet.
