Kaolin is a clay mineral, part of the group of industrial minerals with the chemical composition Al2Si2O5 (OH)4. It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO4) linked through oxygen atoms to one octahedral sheet of alumina (AlO6) octahedra. Rocks that are rich in kaolinite are known as kaolin or china clay.

Kaolin is used in paper filler and coatings, in cosmetics, in ceramics as well as ceramic proppants, in addition to many filler or absorbent applications. Pure kaolin is a relatively soft mineral, with a Mohs hardness of 2 – 2.5. However, mined kaolinite may have a …
Kaolinite–urea complexes were prepared with kaolinite from KGa-1 kaolin by two techniques, mixing and ball-milling at room temperature in water. The intercalation degree was found to be 72% and 69% respectively. Urea-intercalated kaolinite has potential applications in industry, since it change most of the chemical and thermal behaviors.
The amount of kaolinite used for each run was 30 g. Grinding was made at continuous intervals of 15 s, between which the material was mixed. Ground samples were taken after the following grinding periods: 30, 60, 120, 180,300, 400, 600 and 750 s.
