WebClay minerals have a sheet-like structure and are composed of mainly tetrahedrally arranged silicate and octahedrally arranged aluminate groups. Kaolinite is the principal mineral in kaolin clays. It is a 1:1 clay mineral – the basic unit is composed of a 2-dimensional (2D) layer of silicate groups tightly bonded to a 2D layer of aluminate groups. WebJan 1, 2006 · The atomic structure of the clay minerals consists of two basic units, an octahedral sheet and a tetrahedral sheet. The octahedral sheet is comprised of closely packed oxygen's and hydroxyls in which aluminum, iron, and magnesium atoms are arranged in octahedral coordination.

WebThe structure of brucite consists of sheets of MgO 6 octahedra lying in the plane of the x and y axes. The MgO 6 octahedra have H atoms at each apex ( Fig. 1 A ). The layers are stacked so that the H atoms in one layer are opposite the space between three H atoms in the succeeding layer without significant bonding between the layers.
