A hydrous aluminum silicate mineral.
A type of unstable clay often formed from volcanically derived sediments.
Al Si 10(OH). A member of the clay mineral group.
A naturally occurring crystalline mineral that is extracted from kaolin.
hydrous aluminosilicate clay mineral of the 1:1 crystal structure group - - that is, consisting of one silicon tetrahedral sheet and one aluminum oxide-hydroxide octahedral sheet.
nonexpansive clay; — see also ferrallitic
A group of clay minerals formed by weathering or hydrothermal alteration of feldspars and other aluminous silicate minerals;
a crystalline, hydrous silicate of aluminum, the chief constituent of kaolin and some other clays. Kaolinite is polymorphous with dickite and nacrite. [AHDOS
Clay Mineral with a 1 _1 crystal lattice. i.e alternating aluminum octahadral and silicon tetrahedral layers. Usual
Hydrated silicate of alumina represented by the formula Al2O3 · 2 SiO2 2 H2O. It is a white, pearly mineral, crystallizing in a monoclinic system in the form of small, hexagonal plates. Constituent of kaolin, white china clay, used for porcelain, etc.
Kaolinite is a clay mineral with the chemical composition Al2Si2O5(OH)4. It is a layered silicate mineral, with one tetrahedral sheet linked through oxygen atoms to one octahedral sheet of alumina octahedra. Rocks that are rich in kaolinite are known as china clay or kaolin , named after Gaoling ("High Hill") in Jingdezhen, Jiangxi province, China and were traditionally used in the manufacture of porcelain.
