La description
Kaolinite clay occurs in abundance in soils that have formed
from the chemical weathering of rocks in hot, moist climates—for
example in tropical rainforest areas. Comparing soils along a
gradient towards progressively cooler or drier climates, the
proportion of kaolinite decreases, while the proportion of other
clay minerals such as illite (in cooler climates) or smectite (in
drier climates) increases. Such climatically-related differences in
clay mineral content are often used to infer changes in climates in
the geological past, where ancient soils have been buried and
preserved.

The largest use is in the production of paper, including
ensuring the gloss on some grades of paper.
In April ***8, the US Naval Medical Research Institute
announced the successful use of a kaolinite-derived aluminosilicate
nanoparticle infusion in traditional gauze, known commercially as
QuikClot Combat Gauze.[*2]
Kaolin is or was also used:
in ceramics. It is generally the main component in
porcelain.
in toothpaste
as a light diffusing material in white incandescent light
bulbs
in cosmetics
as paint to extend titanium dioxide (TiO2) and modify gloss
levels;
for its semi-reinforcing properties in rubber
in adhesives to modify rheology.[*3]
the production of common smoking pipes in Europe and
Asia
in organic farming, as a spray applied to crops to deter
insect damage, and in the case of apples, to prevent sun
scald.
as whitewash in traditional stone masonry homes in Nepal. The
most common method is to paint the upper part with white Kaolin
clay and the middle with red clay. The red clay may extend to the
bottom, or the bottom may be painted black.
as a filler in Edison Diamond Discs.[*4]
as an indicator in radiological dating since Kaolinite can
contain very small traces of uranium and thorium.
to soothe an upset stomach, similar to the way parrots (and
later, humans) in South America originally used it.[*5] More
recently, industrially-produced kaolinite preparations were
formerly common for treatment of diarrhea; the most common of these
was Kaopectate, which abandoned the use of kaolin in favor of
attapulgite and then (in the United States) bismuth
subsalicylate.
for facial masks or soap[*6]
According to the American National Precast Concrete
Association metakaolin is a supplementary cementitious material
(SCM). When added to a concrete mix, metakaolin accelerates the
hydration of Portland cement.
