Kaolinite

Al2Si2O5(OH)4
Triclinic root IMA approved

Kaolinite is a hydrous aluminum silicate mineral with the chemical formula Al2Si2O5(OH)4. It belongs to the triclinic crystal system and is a member of the kaolin group. This mineral is characterized by its very low hardness of 1 on the Mohs scale, a white streak, and a dull to earthy luster. Its density is relatively low, and it typically appears in white, gray, or pale yellow colors. Kaolinite is a phyllosilicate mineral and is commonly used in ceramics and as a filler in paper and paint due to its fine particle size and chemical inertness.

Overview

Kaolinite is a hydrous aluminum silicate mineral with the chemical formula Al2Si2O5(OH)4. It belongs to the triclinic crystal system and is a member of the kaolin group. This mineral is characterized by its very low hardness of 1 on the Mohs scale, a white streak, and a dull to earthy luster. Its density is relatively low, and it typically appears in white, gray, or pale yellow colors. Kaolinite is a phyllosilicate mineral and is commonly used in ceramics and as a filler in paper and paint due to its fine particle size and chemical inertness.

Geological genesis

Kaolinite is a phyllosilicate mineral typically formed through the chemical weathering of aluminum-rich silicate minerals such as feldspar. It is commonly associated with low-temperature hydrothermal alteration and sedimentary processes, particularly in tropical and subtropical environments where intense weathering occurs.
