Kaolin

Kaolin (hydrated aluminium silie, Al 2 Si 2 O 5 (OH) 4) is the most important of the industrial clays in terms of both consumption and value. Properties of fine particle size, platy shape, inertness, nontoxicity, and high brightness and whiteness make it a most versatile mineral, with appliions in a wide variety of industries. The largest single market, taking ~40% of production, is the ...
