Kaolin yi minerali non-metallic, nto leyo luhlobo lodongwe kunye nelitye lodongwe ikakhulu yakhiwe Kaolinite iqela izimbiwa zodongwe.Ngenxa yembonakalo yayo emhlophe kunye nethambileyo, ikwabizwa ngokuba ngumhlaba weBaiyun.Yathiywa ngeGaoling Village eJingdezhen, kwiPhondo laseJiangxi.

I-kaolin yayo ecocekileyo imhlophe, ithambile kwaye ifana ne-Mollisol, kunye neplastiki elungileyo, ukumelana nomlilo kunye nezinye iimpawu zomzimba kunye neekhemikhali.Ukubunjwa kwayo kweeminerali kuqulunqwe ikakhulu iKaolinite, i-halloysite, i-hydromica, i-Illite, i-Montmorillonite, i-quartz, i-feldspar kunye nezinye iiminerali.I-Kaolin isetyenziswa kakhulu ekwenzeni iphepha, iiseramikhi, kunye nezixhobo zokuchasa, ilandelwa ziingubo zokugquma, izihluzi zerabha, ukumenyezela kwe-enamel, kunye nemathiriyeli ekrwada yesamente emhlophe.Isixa esincinci sisetyenziswa kwiplastiki, ipeyinti, ibala, amavili okusila, iipensile, izithambiso zemihla ngemihla, isepha, izibulali-zinambuzane, amayeza, amalaphu, i-petroleum, imichiza, izinto zokwakha, ukhuselo lwelizwe kunye namanye amacandelo oshishino.
I-Kaolin iye yaba yinto ebalulekileyo yezimbiwa ekrwada kumashishini amaninzi afana ne-papermaking, iiseramikhi, irabha, ubunjineli bemichiza, iingubo, amayeza, kunye nokhuselo lwesizwe.

Ishishini leceramic lelona shishini lakuqala nelona lisetyenziswa kakhulu ekusetyenzisweni kwekaolin.Idosi ngokubanzi yi-20% ukuya kwi-30% yefomula.Indima ye-kaolin kwi-ceramics kukuzisa i-Al2O3, enenzuzo ekubunjweni kwe-mullite, ukuphucula ukuzinza kwayo kweekhemikhali kunye namandla e-sintering.Ngexesha le-sintering, i-kaolin iyabola ukuze yenze i-mullite, yenza isakhelo esiphambili sokuqina komzimba.Oku kunokuthintela ukuguqulwa kwemveliso, ukwandisa ubushushu bokudubula, kunye nokunika umzimba iqondo elithile lobumhlophe.Kwangaxeshanye, i-kaolin ineplastiki ethile, ukubambisana, ukunqunyanyiswa kunye nobuchule bokudibanisa, obunika udongwe lwe-porcelain kunye ne-porcelain glaze kunye nokwakheka kakuhle, okwenza umzimba wodongwe we-porcelain ulungele ukujika, ukugrumba kunye nokwenza.Ukuba isetyenziswe kwiingcingo, inokunyusa ukugquma kunye nokunciphisa ilahleko ye-dielectric.

I-Ceramics ayinayo kuphela imfuneko engqongqo yeplastiki, ukunamathela, ukomisa ukushwabana, ukomisa amandla, i-sintering shrinkage, iipropati ze-sintering, ukumelana nomlilo, kunye nokudubula kobumhlophe be-kaolin, kodwa kubandakanya iipropati zekhemikhali, ngakumbi ubukho bezinto ze-chromogenic ezifana nentsimbi, i-titanium, ubhedu, i-chromium, kunye ne-manganese, ezinciphisa ubumhlophe besithuba sokudubula kwaye zivelise amabala.
Imfuno yesayizi ye-kaolin ye-kaolin ngokuqhelekileyo kukuba i-finer ingcono, ukuze udaka lwe-porcelain lube neplastiki elungileyo kunye namandla omisa.Nangona kunjalo, kwiinkqubo zokuphosa ezifuna ukuphosa ngokukhawuleza, isantya esikhawulezayo se-grouting, kunye nesantya sokuphelelwa ngamanzi emzimbeni, kuyimfuneko ukunyusa ubungakanani bamasuntswana ezithako.Ukongezelela, umahluko kwi-crystallinity ye-Kaolinite kwi-kaolin nayo iya kuchaphazela kakhulu ukusebenza kwezobuchwepheshe bomzimba we-ceramic.Nge-crystallinity enhle, iplastiki kunye nekhono lokudibanisa liya kuba liphantsi, i-shrinkage yokomisa iya kuba yincinci, ukushisa kwe-sintering kuya kuba phezulu, kwaye umxholo wokungcola uya kuncitshiswa;Ngokuchasene noko, iplastiki yayo iphezulu, i-shrinkage yokomisa inkulu, ukushisa kwe-sintering kuphantsi, kwaye umxholo wokungcola ohambelana nawo uphezulu.
