Between the five main minerals found in clay, kaolinite is the most common. Kaolinite holds the chemical composition Al2Si2O5(OH)4 and is an aluminum silicate material with a low “shrink-swell” capacity. It is a soft, white mineral but is often colored orange or red by iron oxide found in

1998-5-13 · Clay minerals are very small, usually less than 4 µm in diameter, and have net negative sur-face charge (Brindley and Brown, 1980). Their high surface area and negative charge, providing large reaction surface and ion-exchange capacity, allow clay minerals to track relatively subtle changes in flu-id chemical composition.

Clay materials are composed of solid, liquid and vapour phases. The solid phases are of mineral and organic phases that make up the framework of the clay materials. The mineralogy can be broadly subdivided into the clay and non-clay minerals, including poorly crystalline, so-called ‘amorphous’ inorganic phases. By definition, minerals are crystalline solids with well-ordered crystal ...

Most of the solid components of the Earth’s crust, i.e. rocks, sediments, clays etc. are largely made up of various mineral species. A mineral species is defined as: A naturally occurring, inorganic, homogeneous solid, having a definite (but not necessarily fixed) chemical composition and a fixed, ordered internal structure, i.e. crystalline.

Chemical composition of clays. Most clay is aluminum oxide, silicon dioxide, and water. These are the primary elements which fuse together to form a ceramic object. However, many additives can go into clay, affecting its sturdiness, color, texture, or firing range. Sand may be added to some clay, for toughness, viscosity, and texture.

In every case the clay composition has to be so that at the 'maturing temperature' it begins to vitrify and the partial melting of some of its components provides the 'glue' to provide its strength. Other chemical changes take place during firing. These include burning off all organic matter often found in many clays, the decomposition of ...
