Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2Si2O5(OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. … See more The defining mechanical property of clay is its plasticity when wet and its ability to harden when dried or fired. Clays show a broad range of water content within which they are highly plastic, from a minimum water content … See more The main groups of clays include kaolinite, montmorillonite-smectite, and illite. Chlorite, vermiculite, talc, and pyrophyllite are sometimes also classified as clay minerals. There are … See more • Argillaceous minerals – Fine-grained aluminium phyllosilicates • Industrial plasticine – Modeling material which is mainly used by automotive design studios • Clay animation – Stop-motion animation made using malleable clay models See more Clay minerals most commonly form by prolonged chemical weathering of silicate-bearing rocks. They can also form locally from hydrothermal activity. Chemical weathering takes place largely by acid hydrolysis due to low concentrations of carbonic acid, … See more Modelling clay is used in art and handicraft for sculpting. Clays are used for making pottery, both utilitarian and decorative, and construction products, such as bricks, walls, and floor … See more • The Clay Minerals Group of the Mineralogical Society • Information about clays used in the UK pottery industry • The Clay Minerals Society See more WebApr 1, 2024 · Clay is an important component of marine sediments and has an important influence on hydrate formation and dissociation. In contrast to quartz sand with a large particle size, the diameter of the clay particles is relatively small, and there is a large amount of adsorbed water on the clay surface owing to the existence of a diffused double layer.
