Clay - Wikipedia
Clay is a type of fine-grained natural soil material containing clay minerals [1] (hydrous aluminium phyllosilicates, e.g. kaolinite, Al 2 Si 2 O 5 (OH) 4). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. [2][3]

What is clay? - Science Learning Hub
Apr 27, 2010 · Clay is a soft, loose, earthy material containing particles with a grain size of less than 4 micrometres (μm). It forms as a result of the weathering and erosion of rocks containing the mineral group feldspar (known as the ‘mother of clay’) over vast spans of time.
Clay mineral - Wikipedia
Clay minerals are hydrous aluminium phyllosilicates (e.g. kaolin, Al 2 Si 2 O 5 4), sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces.

Clay mineral - Chemical, Physical Properties | Britannica
Clay mineral - Chemical, Physical Properties: Depending on deficiency in the positive or negative charge balance (locally or overall) of mineral structures, clay minerals are able to adsorb certain cations and anions and retain them around the outside of the structural unit in an exchangeable state, generally without affecting the basic ...
10.5: Clay Minerals - Geosciences LibreTexts
Nov 24, 2023 · Clay minerals typically only exist as very tiny crystals, so most true clays also conform to the fine-grained meaning of the word “clay”. A clay mineral is a finely crystalline sheet silicate with hydroxyl ions, and in some cases with water as part of the structure.
