Kaolinite is a soft, earthy, usually white, mineral (dioctahedral phyllosilicate clay), produced by the chemical weathering of aluminium silicate minerals like feldspar. It has a low shrink–swell capacity and a low cation-exchange capacity (1–15 meq/100 g).
23 de abr. de 2023 · Kaolinite is a clay mineral with chemical composition Al2Si2O5 (OH)4 and a layered silicate structure. It is an important industrial mineral used in ceramics, paper, paint, rubber and other products.
La caolinita es un mineral de arcilla que forma parte del grupo de minerales industriales, con la composición química Al 2 Si 2 O 5 4 [1] . Se trata de un mineral tipo silicato estratificado, con una lámina de tetraedros unida a través de átomos de oxígeno en una lámina de octaedros de alúmina. [2] Las rocas que son ricas en caolinita son conocidas como caolín o arcilla de China. [3]
Kaolinite is a common and abundant clay mineral with a soft consistency and earthy texture. It is used for pottery, paper, cosmetics, and other industrial purposes, and can form interesting pseudomorphs after other minerals.
