Kaolinite - Wikipedia

Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, part of the group of industrial minerals with the chemical composition Al 2 Si 2 O 5 4.It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO 4) linked through oxygen atoms to one octahedral sheet of alumina (AlO 6) octahedra. Rocks that are rich in kaolinite are known as kaolin / ˈ k eɪ ə l ɪ n / or china clay.

(PDF) ZETA POTENTIAL OF KAOLINITE IN THE PRESENCE OF ...

As the concentration of heavy metal ions increases in the solution, the zeta potential of kaolinite decreases (becomes less negative). Note that at low heavy metal ion concentrations (10−4 M) kaolinite does not give a point of zero charge with any heavy metal ions; however, as the concentration of these ions increase it gives two apparent pzcs.

Silver–kaolinite (AgK) material is prepared as an additive to improve the iodide retention capacity of bentonite. The AgK is prepared by heating kaolinite–silver nitrate mix at 400 °C to study the kaolinite influence on the transition metal ion when reacting at its dehydroxylation temperature.

Kyanite - Wikipedia

It is commonly found in quartz. Although potentially stable at lower pressure and low temperature, the activity of water is usually high enough under such conditions that it is replaced by hydrous aluminosilicates such as muscovite, pyrophyllite, or kaolinite. Kyanite is also known as disthene, rhaeticite and cyanite.
