Metakaolin is a dehydroxylated form of the clay mineral
kaolinite . Rocks that are rich in
kaolinite are known as china clay or kaolin,
Kaynak: MetakaolinBall clays are kaolinitic sedimentary clay s, that commonly consist of 20-80%
kaolinite , 10-25% mica , 6-65% quartz . Localized seam s
Kaynak: Ball clayArgillic alteration is hydrothermal alteration of wall rock which introduces clay mineral s including
kaolinite , smectite and illite .
Kaynak: Argillic alterationGreenalite is a mineral in the
kaolinite -serpentine group with the chemical composition (Fe 2+,Fe 3+)2-3 Si 2 O 5 OH 4 It is a member of
Kaynak: GreenaliteFerrallitisation is the process in which rock is changed into a soil consisting of clay (
kaolinite ) and sesquioxide s, in the form of
Kaynak: FerrallitisationThe cation exchange capacity (CEC) of illite is smaller than that of smectite but higher than that of
kaolinite , typically around 20 – 30
Kaynak: IlliteCrystalline alumino-silica clays: montmorillonite, illite , vermiculite , chlorite ,
kaolinite . Amorphous clays: young mixtures of silica
Kaynak: SoilOther common clay species, and sometimes dominant, are montmorillonite and
kaolinite .
Kaolinite-dominated clays are commonly referred to
Kaynak: BentoniteRiver s in the area have problems with china clay waste materials, mostly
kaolinite , entering the rivers and turning them white.
Kaynak: Gover Streamusually results in the production of low temperature clay minerals into higher temperature polymorphs such as
kaolinite and vermiculite .
Kaynak: Zeolite faciesIn the U.S., kaopectate is now equivalent to a tableted form of Pepto-Bismol , and is no longer made from
kaolinite and pectin .
Kaynak: Kaopectateα-AlO(OH), in a mixture with the two iron oxide s goethite and hematite , the clay mineral
kaolinite , and small amounts of anatase TiO 2.
Kaynak: BauxiteThe composition of porcelain is highly variable, but the clay mineral
kaolinite is often a raw material. Other raw materials can include
Kaynak: PorcelainA 1:1 clay would consist of one tetrahedral sheet and one octahedral sheet, and examples would be
kaolinite and serpentine. A 2:1 clay
