Kaolin is a non-metallic mineral, inova rudzi rwevhu nevhu dombo rinonyanya kuumbwa neboka reKaolinite ivhu zvicherwa.Nekuda kwekuchena kwayo uye kutetepa kutaridzika, inozivikanwa zvakare seBaiyun ivhu.Inotumidzwa zita reGaoling Village muJingdezhen, Jiangxi Province.

Yayo yakachena kaolin ichena, yakapfava uye Mollisol senge, ine yakanaka plasticity, moto kuramba uye zvimwe zvemuviri uye makemikari zvinhu.Kuumbwa kwayo kwemaminerari kunonyanya kuumbwa neKaolinite, halloysite, hydromica, Illite, Montmorillonite, quartz, feldspar uye mamwe maminerari.Kaolin inoshandiswa zvakanyanya mukugadzira mapepa, ceramics, uye refractory zvinhu, inoteverwa neaya, mafirita erabha, enamel glaze, uye chena simende zvinhu.Mari shoma inoshandiswa mupurasitiki, pendi, pigment, mavhiri ekukuya, mapenzura, zvizorwa zvemazuva ese, sipo, mishonga yekuuraya zvipembenene, mishonga yemishonga, machira, peturu, makemikari, zvekuvaka, kudzivirira kwenyika, uye mamwe maindasitiri.

Kaolin zvicherwa zvinoumbwa Kaolinite, dickite, pearl dombo, halloysite uye mamwe Kaolinite sumbu zvicherwa, uye chikuru chicherwa chinoumba Kaolinite.

Iyo Crystal chemistry formula yeKaolinite ndeye 2SiO2 ● Al2O3 ● 2H2O, uye iyo Theoretical chemistry yakagadzirwa ndeye 46.54% SiO2, 39.5% Al2O3, 13.96% H2O.Kaolin zvicherwa ndeye 1: 1 mhando yakaturikidzana silicate, uye crystal inonyanya kuumbwa ne silica tetrahedron uye alumina Octahedron.Iyo silica tetrahedron yakabatanidzwa pamwe chete nemativi maviri-dimensional kutungamira nekugovera vertex angle kuti iite hexagonal grid layer, uye iyo peak okisijeni isingagovanirwe neimwe silica tetrahedron inotarisana nedivi rimwe;Iyo 1: 1 mhando yeyuniti layer inoumbwa nesilicon oxide tetrahedron layer uye aluminium oxide Octahedron layer, iyo inogovera muromo weokisijeni yesilicon oxide tetrahedron layer.
