Kaolinite - Wikipedia

Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, with the chemical composition Al 2 Si 2 O 5 4.It is an important industrial mineral.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.

Surface Charge Properties of Kaolinite | SpringerLink

Feb 01, 1997· The surface charge components of 2 Georgia kaolinites of differing degrees of crystallinity (KGa-1 and KGa-2) were determined using procedures based on charge balance concepts. Permanent structural charge density (σ0) was determined by measuring the surface excess of Cs, which is highly selective to permanent charge sites. The values of σ0 determined were -6.3 ±0.1 and -13.6 ± 0.5 mmol kg ...

Reading: Physical Characteristics of Minerals | Geology

There are some properties that only help to distinguish a small number of minerals, or even just a single mineral. An example of such a special property is the effervescent reaction of calcite to a weak solution of hydrochloric acid (5% HCl). Calcite fizzes or effervesces as the HCl solution dissolves it and creates CO 2 gas. Calcite is easy to ...
