Kaolin
A fine usually white clay that is used in ceramics and refractories, as a filler or extender, and in medicine especially as an adsorbent in the treatment of diarrhea.
It is a naturally occurring clay substance mostly found in soils that have developed from the chemical weathering of rocks in hot, moist climates. A good example of such a climate is the tropical rain forest. It is also called China clay, White clay, White Cosmetic clay, Hydrated Aluminum Silicate, Kaolinite clay amongst other names
Kaolin/ Kaolinite Clay
Physical Properties of Kaolin Clay
China clay is often white in color, especially in its pure natural state. However, the color may vary when it occurs in combination with other elements. For instance, kaolin clay appears pink-orange in combination with iron oxide, and yellow or light orange when in combination with aluminum silicate (feldspar). Sometimes, white clay may appear brown when mixed with sand. See more kaolin clay varieties basing on colors.
White clay occurs in crystal forms of varying sizes. The crystals of kaolinite as seen under electron microscope are hexagonal in shape arranged in platy layers. Kaolin clay is soft powder and earthy in texture. It has low capacity to shrink and swell, which means that it has low extent of expanding when wet and low capabilities of contracting when dry.
