Kaolin ivhu risiri resimbi, iro riri rudzi rwedombo revhu nevhu rine minerals dzevhu dzeboka reKaolinite. Nekuda kwechitarisiko chayo chena uye chakapfava, inozivikanwawo sevhu reBaiyun. Yakatumidzwa zita kubva kuGaoling Village muJingdezhen, Jiangxi Province.

Kaolin yayo yakachena yakachena, ine hunyoro uye yakafanana neMollisol, ine plasticity yakanaka, inodzivirira moto uye zvimwe zvinhu zvemuviri uye zvemakemikari. Muumbirwo wayo wezvicherwa unonyanya kuumbwa neKaolinite, halloysite, hydromica, Illite, Montmorillonite, quartz, feldspar nezvimwe zvicherwa. Kaolin inoshandiswa zvakanyanya mukugadzira mapepa, zveceramics, uye zvinhu zvinoramba kusimba, ichiteverwa nependi, rabha fillers, enamel glazes, uye chena simende zvinhu zvakabikwa. Chidimbu chinoshandiswa mupurasitiki, pendi, pigments, grinding wheels, mapenzura, zvizoro zvezuva nezuva, sipo, mishonga yezvipembenene, mishonga, machira, peturu, makemikari, zvinhu zvekuvaka, dziviriro yenyika, nezvimwe zvikamu zveindasitiri.

Zvicherwa zveKaolin zvinoumbwa neKaolinite, dickite, pearl stone, halloysite nezvimwe zvicherwa zveKaolinite cluster, uye chikamu chikuru chezvicherwa iKaolinite.

Fomura yekristalo yeKaolinite i2SiO2 ● Al2O3 ● 2H2O, uye chimiro chayo cheTheoretical chemistry i46.54% SiO2, 39.5% Al2O3, 13.96% H2O. Maminerari eKaolin ndeemhando ye1:1 layered silicate, uye kristalo inonyanya kuumbwa ne silica tetrahedron ne alumina Octahedron. Silica tetrahedron yakabatana nedivi re two-dimensional nekugovana vertex angle kuti igadzire hexagonal grid layer, uye peak oxygen isingagovaniswe ne silica tetrahedron yega yega yakatarisana nedivi rimwe; Iyo 1:1 type unit layer inoumbwa ne silicon oxide tetrahedron layer ne aluminium oxide Octahedron layer, iyo inogovana oksijeni ye silicon oxide tetrahedron layer.
