Kaolin clay is chemically hydrated aluminium silicate and structurally unmodified. Water washed kaolin is made by slurrying the raw clay and then centrifuging or hydrocycloning it to remove impurities. Chemical bleaching is done to improve the brightness of the kaolin .
Kaolin is a form of clay. Clays are formed by the weathering of rocks. Weathering of rocks can be classified as physical or chemical process. In case of kaolin, the chemical reaction between water, carbon dioxide and feldspar (rock) gives rise to kaolin clay deposits. Feldspar (Rock) + Water + Carbon Dioxide (Gas) > Kaolin (Clay)
Calcined kaolin clay is produced when hydrous kaolin is heated to over 1000°C. The crystal structure of the calcined clay becomes amorphous. The rearrangement of the crystal structure of kaolin which comes with a loss of hydroxyl groups makes calcined clays harder, more abrasive and more porous than their waterwashed counterparts.
paragraphs describe the steps used to process each of the six categories of clay. Table summarizes these processes by clay type. Kaolin Kaolin is both dry and wetprocessed. The dry process is simpler and produces a lower quality product than the wet process. Dryprocessed kaolin is used mainly in the rubber industry, and

Kaolin clay is a fine textured, highly absorbent mineral compound mined in locations all over the world. About 50 percent of the kaolin produced is used in the ...
Kaolin clay sources can vary significantly, with a number of accompanying impurities possible. Similarly, chemical and physical properties of kaolin sources vary as well. As a result, varying sources of kaolin often respond to calcination in different ways, making it somewhat unpredictable. Calcination Parameters
China Clay is also known as kaolin white clay. Primary clay formed by natural kaolinisation process. It is formed by the decomposition of some part of feldspar mineral. White in colour, Used in the ceramic slip casting process, pressing processes and forming process as a body former and filler.
Kaolin, or ''china clay'' as it is commonly called, is a hydrated aluminum silicate crystalline mineral formed over many millions of years by the hydrothermal decomposition of granite rocks. Hydrous kaolin is characterized by its fine particle size, platelike or lamellar particle shape and chemical inertness.
