ʻO kaolin he mineral non-metallic, ʻo ia ka pālolo a me ka pālolo pōhaku i haku nui ʻia me nā minerala 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.

ʻO kona kaolin maʻemaʻe he keʻokeʻo, palupalu, a palupalu i ke ʻano, me nā waiwai kino a me nā mea kemika maikaʻi e like me ka plasticity a me ke kūpaʻa ahi.ʻO ka nui o kāna hui ʻana i nā minerale e like me kaolinite, halloysite, hydromica, illite, montmorillonite, a me ka quartz a me ka feldspar.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.

ʻO nā minerala i loko o ka kaolin ma ke ʻano, ua māhele nui ʻia i nā minerala pālolo a me nā minerala pālolo ʻole.ʻO ka nui o nā minelala pālolo ka hui pūʻulu kaolinite a me kahi mea liʻiliʻi o ka montmorillonite, mika, a me ka chlorite;ʻO nā minelala pālolo ʻole ka nui o nā feldspar, quartz, a me nā hydrates, a me kekahi mau mea hao e like me ka hematite, siderite, limonite, titanium mineral e like me rutile, a me nā mea kūlohelohe e like me nā mea kanu.ʻO ke kumu nui e hoʻoholo ai i ka hana o ka kaolin ʻo nā minerala pālolo.

Ua lilo ʻo Kaolin i mea koʻikoʻi koʻikoʻi no ka nui o nā ʻoihana e like me ka hana pepa, ka seramika, ka pahu, ka ʻenekinia kemika, nā uhi, nā lāʻau lapaʻau, a me ka pale aupuni.

ʻO ka ʻoihana seramika ka ʻoihana mua loa a hoʻohana nui ʻia no ka hoʻohana ʻana i kaolin.ʻO ka maʻamau maʻamau he 20% a 30% o ke kumu.ʻO ke kuleana o kaolin i nā seramika e hoʻolauna iā Al2O3, he mea pono ia no ka hoʻokumu ʻana i ka mullite, e hoʻomaikaʻi i kona kūpaʻa kemika a me ka ikaika sintering.I ka wā o ka sintering, hoʻoheheʻe ʻia ka kaolin e lilo i mullite, e hana ana i ke kumu nui no ka ikaika o ke kino.Hiki i kēia ke pale i ka deformation o ka huahana, hoʻonui i ka mahana ahi, a hāʻawi pū i ke kino i kahi ʻano keʻokeʻo.I ka manawa like, loaʻa ka kaolin i kahi pae o ka plasticity, adhesion, suspension, a me ka hiki ke hoʻopaʻa ʻana, e hoʻopiha ana i ka lepo porcelain a me ka glaze me ka formability maikaʻi, e hoʻomaikaʻi ai i ke kino lepo seramika no ke kino o ke kaʻa a me ka grouting, e maʻalahi ke hana.Inā hoʻohana ʻia i nā uea, hiki ke hoʻonui i ka insulation a hōʻemi i ka nalowale dielectric.

ʻAʻole wale nā ​​koi koʻikoʻi o nā Ceramics no ka plasticity, adhesion, maloʻo shrinkage, maloʻo ikaika, sintering shrinkage, sintering waiwai, ahi kū'ē, a me ka hope pana keʻokeʻo o kaolin, akā, e pili ana i kemika waiwai, o ka oi aku ka hele ana o chromogenic mea e like me ka hao, ʻO ka titanium, ke keleawe, ka chromium, a me ka manganese, e hōʻemi ana i ka keʻokeʻo ma hope o ke kī ʻana a hoʻopuka i nā kiko.

ʻO ke koi no ka nui o ka ʻāpana o ka kaolin ʻoi aku ka maikaʻi o ka ʻoi aku ka maikaʻi, no laila ʻoi aku ka maikaʻi o ka ʻōpala porcelain a me ka ikaika maloʻo.Eia nō naʻe, no ka hoʻolei ʻana i nā kaʻina hana e koi ai i ka hoʻolei wikiwiki ʻana, ka wikiwiki o ka grouting wikiwiki, a me ka wikiwiki dehydration, pono e hoʻonui i ka nui o nā mea hana.Eia kekahi, ʻo ka ʻokoʻa i ka crystallinity o kaolinite i kaolin e hoʻopilikia nui i ka hana o ka porcelain billets.Inā maikaʻi ka crystallinity, haʻahaʻa ka plasticity a me ka hiki ke hoʻopaʻa ʻia, liʻiliʻi ka maloʻo maloʻo, kiʻekiʻe ke kiʻekiʻe o ka sintering, a hoʻemi ʻia hoʻi ka ʻike haumia;ʻO ka mea ʻē aʻe, ʻoi aku ka kiʻekiʻe o kona plasticity, ʻoi aku ka nui o ka hoʻomaloʻo ʻana, ʻoi aku ka haʻahaʻa o ka sintering, a ʻoi aku ka kiʻekiʻe o ka ʻike haumia.
