kaolin
A fine clay mass, usually white in color, and made
up principally of clay mineral kaolinite. The
kaolin clays have the approximate formula (2SiO
2 . 2H 2 O); however, they
also contain small amounts of other minerals, as
well as impurities. Kaolin is used extensively as
a coating and filling clay in the manufacture of
paper. See also: PAPER
