I-Kaolin iyi-mineral non-metallic, okuwuhlobo lwedwala lobumba nobumba ikakhulukazi elakhiwe amaminerali obumba weqembu le-Kaolinite.Ngenxa yokubukeka kwayo okumhlophe nokuthambile, yaziwa nangokuthi inhlabathi ye-Baiyun.Iqanjwe ngeGaoling Village eJingdezhen, esifundazweni saseJiangxi.

I-kaolin yayo emsulwa imhlophe, intekenteke futhi ifana ne-Mollisol, inopulasitiki omuhle, ukumelana nomlilo nezinye izinto ezibonakalayo namakhemikhali.Ukwakheka kwayo kwamaminerali ikakhulukazi kwakhiwe i-Kaolinite, i-halloysite, i-hydromica, i-Illite, i-Montmorillonite, i-quartz, i-feldspar namanye amaminerali.I-Kaolin isetshenziswa kakhulu ekwenzeni iphepha, izitsha zobumba, kanye nezinto eziphikisayo, kulandelwa izinto zokumboza, izigcwalisi zenjoloba, okoqweqwe lwawo koqweqwe lwawo, kanye nezinto zokusetshenziswa zikasimende omhlophe.Imali encane isetshenziswa kupulasitiki, upende, izingulube, amasondo okugaya, amapensela, izimonyo zansuku zonke, insipho, izibulala-zinambuzane, imithi, izindwangu, i-petroleum, amakhemikhali, izinto zokwakha, ukuvikela izwe kanye neminye imikhakha yezimboni.

Amaminerali e-Kaolin akhiwe nge-Kaolinite, i-dickite, i-pearl stone, i-halloysite namanye amaminerali eqoqo le-Kaolinite, futhi ingxenye enkulu yamaminerali i-Kaolinite.

I-Crystal chemistry formula ye-Kaolinite yi-2SiO2 ● Al2O3 ● 2H2O, futhi ukwakheka kwayo kwe-Theoretical chemistry yi-46.54% SiO2, 39.5% Al2O3, 13.96% H2O.Amaminerali e-Kaolin ayingxenye ye-1: 1 yohlobo lwe-silicate enezingqimba, futhi i-crystal yakhiwe ikakhulukazi i-silica tetrahedron ne-alumina Octahedron.I-silica tetrahedron ixhunywe eduze kwendlela enezinhlangothi ezimbili ngokwabelana nge-engeli ye-vertex ukuze yakhe ungqimba lwegridi ene-hexagonal, futhi umoya-mpilo ophakeme ongabelwe yi-silica tetrahedron ngayinye ubheke ohlangothini olulodwa;Isendlalelo seyunithi yohlobo olu-1:1 lwakhiwe ngelendlalelo ye-silicon oxide tetrahedron kanye nongqimba lwe-aluminium oxide Octahedron, olwabelana ngezwe le-oksijini ye-silicon oxide tetrahedron.
