IKaolin yiminerali engeyoyesinyithi, uhlobo lwelitye lodongwe nodongwe elilawulwa yiminerali yodongwe lwekaolinite. Ngenxa yokuba imhlophe kwaye ithambile, ikwabizwa ngokuba ngumhlaba omhlophe wamafu. Ithiywe ngegama leGaoling Village, eJingde Town, kwiPhondo laseJiangxi.

I-kaolin yayo ecocekileyo imhlophe, ithambile kwaye ithambile njengodongwe, kwaye ineempawu ezintle zomzimba nezekhemikhali ezifana ne-plasticity kunye nokumelana nomlilo. Ulwakhiwo lwayo lwezimbiwa luquka ikakhulu i-kaolinite, i-halloysite, i-hydromica, i-illite, i-montmorillonite, i-quartz, i-feldspar kunye nezinye izimbiwa. I-Kaolin inoluhlu olubanzi lokusetyenziswa, olusetyenziswa kakhulu ekwenzeni iphepha, iiseramikhi kunye nezinto ezichaseneyo, kulandele iingubo, izizalisi zerabha, iiglaze ze-enamel kunye nezinto eziluhlaza zesamente emhlophe, kunye nesixa esincinci esisetyenziswa kwiiplastiki, iipeyinti, ii-pigment, amavili okugaya, iipensele, izinto zokuthambisa zemihla ngemihla, isepha, izibulali-zinambuzane, amayeza, impahla yelaphu, ipetroli, iikhemikhali, izixhobo zokwakha, ukhuselo lwesizwe kunye namanye amacandelo emizi-mveliso.
Ukukhanya Okumhlophe Okugoqiweyo
Ubumhlophe yenye yezona parameter ziphambili zokusebenza kobuchwepheshe be-kaolin, kwaye i-kaolin enobumsulwa obuphezulu imhlophe. Ubumhlophe be-kaolin bahlulwe baba bumhlophe bendalo kunye nobumhlophe emva kokuba i-calcination. Kwizinto eziluhlaza ze-ceramic, ubumhlophe emva kokuba i-calcination ibaluleke ngakumbi, kwaye okukhona ubumhlophe be-calcination buphezulu, kokukhona umgangatho uba ngcono. Itekhnoloji ye-ceramic ichaza ukuba ukomisa kwi-105°C ngumgangatho wokubeka amanqaku obumhlophe bendalo, kwaye ukuba i-calcination kwi-1300°C ngumgangatho wokubeka amanqaku obumhlophe be-calcination. Ubumhlophe bunokulinganiswa ngemitha yokulinganisa ubumhlophe. Imitha yokulinganisa ubumhlophe sisixhobo esilinganisa ukukhanya okunobude obuyi-3800-7000Å (oko kukuthi i-Angstrom, 1 Angstrom = 0.1 nm). Kwimitha yokulinganisa ubumhlophe, thelekisa ukukhanya kwesampulu eza kuvavanywa ngesampulu esemgangathweni (njenge-BaSO4, i-MgO, njl.njl.), oko kukuthi, ixabiso lobumhlophe (umzekelo, ubumhlophe obuyi-90 buthetha i-90% yokukhanya kwesampulu esemgangathweni).

Ukukhanya yipropathi yenkqubo efana nobumhlophe, obulingana nobumhlophe obuphantsi kwemitha yokukhanya kwe-4570Å (Angstrom).

Umbala we-kaolin unxulumene kakhulu nee-oxide zesinyithi okanye izinto eziphilayo ezikuyo. Ngokubanzi, iqulethe i-Fe2O3, ebomvu nemdaka ngebala; iqulethe i-Fe2+, eluhlaza okwesibhakabhaka kunye noluhlaza okhanyayo; iqulethe i-MnO2, emdaka ngebala; iqulethe izinto eziphilayo, ezimthubi ngebala, ezingwevu, eziluhlaza okwesibhakabhaka, nezimnyama. Ukubakho kwezi zinto zingcolileyo kunciphisa ubumhlophe bendalo be-kaolin, kwaye iiminerali ze-iron kunye ne-titanium nazo zichaphazela ubumhlophe obufakwe kwi-calcium, zibangele amabala okanye amanxeba kwi-porcelain.
