IKaolin yiminerali engeyoyesinyithi, elilitye lodongwe nodongwe elenziwe ikakhulu ziiminerali zodongwe zeqela le-kaolinite. Ngenxa yembonakalo yayo emhlophe nethambileyo, ikwaziwa njengomhlaba weBaiyun. Ithiywe ngegama leGaoling Village eJingdezhen, kwiPhondo laseJiangxi.

I-kaolin yayo ecocekileyo imhlophe, ithambile, kwaye ithambile ngobume bayo, ineempawu ezintle zomzimba nezekhemikhali ezifana ne-plasticity kunye nokumelana nomlilo. Ulwakhiwo lwayo lweminerali luquka ikakhulu iiminerali ezifana ne-kaolinite, i-halloysite, i-hydromica, i-illite, i-montmorillonite, kunye ne-quartz kunye ne-feldspar. I-Kaolin isetyenziswa kakhulu ekwenzeni iphepha, iiseramikhi, kunye nezinto ezichaseneyo, ilandelwa zizinto zokugquma, izizalisi zerabha, iiglaze ze-enamel, kunye nezinto eziluhlaza zesamente emhlophe. Isixa esincinci sisetyenziswa kwiplastiki, ipeyinti, ii-pigment, amavili okugaya, iipensele, izinto zokuthambisa zemihla ngemihla, isepha, izibulali-zinambuzane, amayeza, amalaphu, ipetroli, iikhemikhali, izixhobo zokwakha, ukhuselo lwesizwe, kunye namanye amacandelo emizi-mveliso.

Iiminerali ezikwi-kaolin kwindalo zahlulwe kakhulu zibe ziiminerali zodongwe kunye neeminerali ezingezizo ezodongwe. Iiminerali zodongwe ziquka ikakhulu iiminerali zeqela le-kaolinite kunye nenani elincinci le-montmorillonite, i-mica, kunye ne-chlorite; Iiminerali ezingezizo ezodongwe ziquka ikakhulu i-feldspar, i-quartz, kunye ne-hydrates, kunye nezinye iiminerali zesinyithi ezifana ne-hematite, i-siderite, i-limonite, iiminerali ze-titanium ezifana ne-rutile, kunye nezinto eziphilayo ezifana neefayibha zezityalo. Into ephambili echaza ukusebenza kwe-kaolin ziiminerali zodongwe.

I-Kaolin ibe yinto ebalulekileyo kwi-mineral complex kwiinkampani ezininzi ezifana nokwenza iphepha, ii-ceramics, irabha, ubunjineli beekhemikhali, ii-coating, amayeza, kunye nokhuselo lwesizwe.

Ishishini le-ceramic lelona shishini liqalayo nelisetyenziswa kakhulu ekusetyenzisweni kwe-kaolin. Umthamo oqhelekileyo yi-20% ukuya kwi-30% yefomyula. Indima ye-kaolin kwi-ceramics kukwazisa i-Al2O3, eluncedo ekwakhiweni kwe-mullite, iphucula uzinzo lwayo lweekhemikhali kunye namandla okusila. Ngexesha lokusila, i-kaolin iyabola ukuze yenze i-mullite, yenze isakhelo esiphambili samandla omzimba. Oku kunokuthintela ukuguquka kwemveliso, kwandise ubushushu bokudubula, kwaye kunike umzimba inqanaba elithile lobumhlophe. Kwangaxeshanye, i-kaolin inomlinganiselo othile we-plasticity, ukunamathela, ukumiswa, kunye nokukwazi ukubopha, inika udaka lwe-porcelain kunye ne-glaze ukwakheka okuhle, okwenza umzimba wodaka lwe-ceramic ube luncedo emzimbeni wesithuthi kunye ne-grouting, okwenza kube lula ukuyila. Ukuba isetyenziswa kwiingcingo, inokunyusa ubushushu kwaye inciphise ukulahleka kwe-dielectric.

Iiseramikhi azinazo nje kuphela iimfuno ezingqongqo zeplastiki, ukunamathela, ukushwabana kokomisa, amandla okomisa, ukushwabana kokusila, iimpawu zokusila, ukumelana nomlilo, kunye nobumhlophe emva kokudubula kwekaolin, kodwa zikwabandakanya iimpawu zeekhemikhali, ingakumbi ubukho bezinto zechromogenic ezifana nentsimbi, i-titanium, i-copper, i-chromium, kunye ne-manganese, ezinciphisa ubumhlophe emva kokudubula kwaye zivelise amabala.

Imfuneko yobukhulu beesuntswana ze-kaolin ngokubanzi kukuba xa zicolekile ngcono, ukuze udaka lwe-porcelain lube ne-plasticity elungileyo kunye namandla okomisa. Nangona kunjalo, kwiinkqubo zokuphosa ezifuna ukuphoswa ngokukhawuleza, isantya sokugrutha esikhawulezileyo, kunye nesantya sokuphelelwa ngamanzi emzimbeni, kuyimfuneko ukwandisa ubungakanani beesuntswana zezithako. Ukongeza, umahluko kwi-crystallinity ye-kaolinite kwi-kaolin uya kuchaphazela kakhulu ukusebenza kwenkqubo yee-billets ze-porcelain. Ukuba i-crystallinity ilungile, i-plasticity kunye nokukwazi ukubopha kuphantsi, ukuncitshiswa kokomisa kuncinci, ubushushu bokuncitshiswa buphezulu, kwaye umxholo wokungcola nawo unciphile; Ngokwahlukileyo koko, i-plasticity yayo iphezulu, ukuncitshiswa kokomisa kukhulu, ubushushu bokuncitshiswa buphantsi, kwaye umxholo wokungcola ohambelanayo nawo uphezulu.
