Kaolinite minerals yog tsim los ntawm kaolinite, dickite, perlite, halloysite, thiab lwm yam kaolinite pawg minerals, nrog kaolinite yog cov ntxhia tseem ceeb.
Cov tshuaj siv lead ua kua mis ntawm kaolinite yog 2SiO2·Al2O3·2H2O, thiab nws cov theoretical tshuaj muaj pes tsawg leeg yog 46.54% SiO2, 39.5% Al2O3, thiab 13.96% H2O. Kaolinite cov zaub mov muaj nyob rau hauv 1: 1 hom txheej txheej silicate. Cov crystals yog tsim los ntawm silicon{17}}oxygen tetrahedra thiab txhuas{18}}oxygen octahedra. Cov silicon-oxygen tetrahedra txuas nrog rau ob- qhov taw qhia ntawm qhov sib koom los ntawm kev sib faib cov vertices los ua ib txheej hexagonal grid. Lub unshared apexes ntawm silicon-oxygen tetrahedra tag nrho ntawm ib sab. Cov apexes ntawm silicon-oxygen tetrahedra sib koom los ntawm silicon-oxygen octahedra tsim 1: 1 hom chav tsev txheej txheej.
