kaolinite mineral

KAOLINITE (Aluminum Silicate Hydroxide)

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.

Kaolinite - an overview | ScienceDirect Topics

Kaolinite is described as a 1:1 clay mineral consisting of two layers joined through an apical oxygen. One layer is known as the siloxane layer and consists of silicon tetrahedra joined in an hexagonal array. This layer is coupled to a gibbsite-like layer consisting of octahedral aluminium bonded to four OH units and two oxygen atoms.
