I-Kaolin iyiminerali engeyona eyensimbi, okuwuhlobo lwedwala lobumba nobumba oluhlanganiswe kakhulu ngamaminerali obumba eqembu le-Kaolinite. Ngenxa yokubukeka kwayo okumhlophe nokuthambile, yaziwa nangokuthi inhlabathi ye-Baiyun. Iqanjwe ngegama leGaoling Village eJingdezhen, eSifundazweni saseJiangxi.

I-kaolin yayo emsulwa imhlophe, ithambile futhi ifana ne-Mollisol, ine-plasticity enhle, ukumelana nomlilo kanye nezinye izakhiwo zomzimba nezamakhemikhali. Ukwakheka kwayo kwamaminerali kwakhiwe kakhulu yi-Kaolinite, i-halloysite, i-hydromica, i-Illite, i-Montmorillonite, i-quartz, i-feldspar kanye nezinye izimbiwa. I-Kaolin isetshenziswa kabanzi ekwenzeni iphepha, izinto zobumba, nezinto eziphikisayo, kulandelwa ukumbozwa, izigcwalisi zerabha, ama-enamel glaze, kanye nezinto zokusetshenziswa zesimende esimhlophe. Inani elincane lisetshenziswa kupulasitiki, upende, imibala, amasondo okugaya, amapensela, izimonyo zansuku zonke, insipho, izibulala-zinambuzane, imithi, izindwangu, uphethiloli, amakhemikhali, izinto zokwakha, ukuvikela izwe, kanye neminye imikhakha yezimboni.
I-Kaolin isibe yinto ebalulekile yamaminerali emikhakheni eminingi efana nokwenza amaphepha, izinto zobumba, irabha, ubunjiniyela bamakhemikhali, ukumbozwa, imithi kanye nokuvikela izwe.

Imboni ye-ceramic iyona mboni yokuqala nesetshenziswa kakhulu ekusetshenzisweni kwe-kaolin. Umthamo ojwayelekile ungama-20% kuya kuma-30% efomula. Indima ye-kaolin ku-ceramics ukwethula i-Al2O3, ezuzisa ukwakheka kwe-mullite, ithuthukise ukuzinza kwayo kwamakhemikhali kanye namandla okusila. Ngesikhathi sokusila, i-kaolin iyabola ukuze yakhe i-mullite, yakhe uhlaka oluyinhloko lwamandla omzimba. Lokhu kungavimbela ukuguquka komkhiqizo, kwandise izinga lokushisa lokudubula, futhi kunikeze umzimba izinga elithile lobumhlophe. Ngesikhathi esifanayo, i-kaolin inamandla athile okuqina, ukuhlangana, ukumiswa kanye nekhono lokubopha, okunikeza ubumba lwe-porcelain kanye ne-porcelain glaze ukwakheka okuhle, okwenza umzimba wobumba lwe-porcelain ube lula ukuguqula, ukusonta kanye nokwakheka. Uma isetshenziswa ezintanjeni, ingandisa ukufudumala futhi inciphise ukulahleka kwe-dielectric.

I-ceramics ayinazo nje kuphela izidingo eziqinile ze-plasticity, ukunamathela, ukuncipha kokomisa, amandla okomisa, ukuncipha kokusila, izakhiwo zokusila, ukumelana nomlilo, kanye nobumhlophe be-kaolin ngemuva kokudubula, kodwa futhi ihilela izakhiwo zamakhemikhali, ikakhulukazi ukuba khona kwezinto ezibangela i-chromogenic njengensimbi, i-titanium, ithusi, i-chromium, kanye ne-manganese, okunciphisa ubumhlophe be-post-shooting futhi kukhiqize amabala.
Isidingo sosayizi wezinhlayiya ze-kaolin ngokuvamile ukuthi uma zincane kakhulu, ukuze udaka lwe-porcelain lube ne-plasticity enhle namandla okomisa. Kodwa-ke, ngezinqubo zokubumba ezidinga ukubumba okusheshayo, isivinini sokugxusha esisheshayo, kanye nesivinini sokuphelelwa amanzi emzimbeni, kuyadingeka ukwandisa usayizi wezinhlayiya zezithako. Ngaphezu kwalokho, umehluko ekubunjweni kwe-Kaolinite ku-kaolin uzothinta kakhulu ukusebenza kobuchwepheshe bomzimba we-ceramic. Ngobunhlayiya obuhle, ubunhlayiya kanye nekhono lokubopha lizoba liphansi, ukubunjwa kokomisa kuzoba kuncane, izinga lokushisa lokubunjwa lizoba liphezulu, kanye nokuqukethwe kokungcola nakho kuzoncishiswa; Ngokuphambene nalokho, ubunhlayiya bayo buphezulu, ukubunjwa kokomisa kukhulu, izinga lokushisa lokubunjwa liphansi, kanye nokuqukethwe kokungcola okuhambisanayo nakho kuphakeme.
