WHAT IS KAOLIN? Kaolin or china clay is a commercial clay composed principally of the hydrated aluminosilicate clay mineral kaolinite. The commercial value of kaolin is based on the mineral's whiteness and its fine, controllable particle size. Particle size affects fluidity, strength, plasticity, colour, abrasiveness and ease of dispersion.

Kaolinite was the dominant clay mineral in the kaolin deposits and occurrences in Africa with smectite and illite in major quantities, as well as a number of non-clay minerals commonly present in kaolins. Major applications of the kaolins included ceramics, bricks, earthenware, coating, paint, and functional filler.

Kaolin is an industrial mineral used in a wide variety of applications due to its crystalline structure, mineral and elemental composition.

Kaolin is a hydrated aluminum silicate crystalline mineral (kaolinite, Al2(Si2O5)(OH)4). It was termed 'China clay ' from its use in China, formed commonly from weathered granite or hydrothermal activity. It is typical of three main geological environments: (1) weathering profiles; (2) hy-drothermal alterations; and (3) sedimentary rocks.
