ʻO Kaolin kahi mineral non-metallic, ʻo ia ke ʻano o ka pālolo a me ka pālolo pōhaku i haku nui ʻia me nā minela pālolo hui Kaolinite.Ma muli o kona ʻano keʻokeʻo a palupalu, ʻike ʻia ʻo ia ʻo Baiyun lepo.Ua kapa ʻia ma hope o Gaoling Village ma Jingdezhen, Jiangxi Province.

He keʻokeʻo kona kaolin maʻemaʻe, palupalu a like me Mollisol, me ka plasticity maikaʻi, ke kūpaʻa ahi a me nā waiwai kino a me nā mea kemika.ʻO ka mea nui o kona ʻano mineral me Kaolinite, halloysite, hydromica, Illite, Montmorillonite, quartz, feldspar a me nā minerala ʻē aʻe.Hoʻohana nui ʻia ʻo Kaolin i ka hana pepa, keramika, a me nā mea refractory, a ukali ʻia e nā uhi, nā mea hoʻopihapiha hoʻopihapiha, enamel glazes, a me nā mea waiwai sima keʻokeʻo.Hoʻohana ʻia kahi mea liʻiliʻi i ka plastic, pena, pigments, wili huila, penikala, nā mea hoʻonaninani i kēlā me kēia lā, kopa, pesticides, pharmaceuticals, textiles, petroleum, chemical, building materials, national defense, a me nā ʻoihana ʻoihana ʻē aʻe.

Hoʻokumu ʻia nā minerala Kaolin me Kaolinite, dickite, pōhaku momi, halloysite a me nā minerala puʻupuʻu Kaolinite ʻē aʻe, a ʻo ka mea mineral nui ʻo Kaolinite.

ʻO ke kinikini Crystal formula o Kaolinite ʻo 2SiO2 ● Al2O3 ● 2H2O, a ʻo kāna haku mele Theoretical 46.54% SiO2, 39.5% Al2O3, 13.96% H2O.No ka 1:1 ʻano ʻano ʻenela ʻo Kaolin ka silicate layered, a ʻo ke aniani ka nui o ka silica tetrahedron a me ka alumina Octahedron.Hoʻohui ʻia ka silica tetrahedron ma ka ʻaoʻao ʻelua-dimensional ma ke kaʻana like ʻana i ke kihi vertex e hana i kahi papa hexagonal grid, a ʻo ka oxygen kiʻekiʻe ʻaʻole i kaʻana like ʻia e kēlā me kēia silica tetrahedron e alo i kekahi ʻaoʻao;Hoʻokumu ʻia ka papa ʻāpana ʻano 1:1 me ka papa silicon oxide tetrahedron a me ka alumini oxide Octahedron layer, e kaʻana like ana i ka oxygen tip o ka papa silicon oxide tetrahedron.
