Kaolini, kaolini ya calcium, kaolini yogejwe, metakaolini.

Imikoreshereze ya kaolin irimo:
Nk'amabuye y'agaciro akenewe mu nganda nyinshi, nko gukora impapuro, ibumba, kawurute, inganda zikora imiti, gusiga irangi, ubuvuzi no kurinda igihugu, kaolini ifite uburyo bwo gukora ibintu mu buryo bwa pulasitiki, butuma umubiri w'ibumba uba mwiza mu guhinduranya, gusya no gukora.

Akamaro ka kaolin mu byuma bya keramike ni ukongeramo Al2O3, ituma habaho mullite kandi ikongera ubushobozi bwayo bwo kudahinduka no gutwika.

Mu gihe cyo gusya, kaolini irabora ikavamo mullite, igakora urwego rw'ingenzi rw'imbaraga z'icyatsi kibisi, bishobora gukumira guhinduka kw'ibicuruzwa, kongera ubushyuhe bwo kurasa, no gutuma umubiri w'icyatsi ugira umweru runaka.

Metakaolin (MK mu magambo ahinnye) ni silicate ya aluminiyumu idakora (Al2O3 · 2SiO2, AS2 mu magambo ahinnye) ikorwa no kubura amazi kwa kaolini (Al2O3 · 2SiO2 · 2H2O, AS2H2 mu magambo ahinnye) ku bushyuhe bukwiye (600 ~ 900 ℃). Kaolini igizwe n'imiterere ya silicate ifite ibice, kandi ibice bifatanye na van der Waals, aho ioni za OH ziba zifatanye cyane. Iyo kaolini ishyushye mu kirere, imiterere yayo ihinduka inshuro nyinshi. Iyo ishyushye kugeza kuri 600 ℃, imiterere ya kaolini ifite ibice izasenyuka bitewe no kubura amazi, bigatuma metakaolini ihinduka ifite kristali nke. Kubera ko imiterere ya molekile ya metakaolini idahuye neza, igaragaza imiterere ya thermodynamic metastable kandi ifite ubushobozi bwo gukaraba mu gihe cyo gushyuha gukwiye.

Metakaolin ni ubwoko bw'ubuvange bw'amabuye y'agaciro bukora cyane. Ni silicate ya aluminiyumu idahinduka igizwe na kaolin nziza cyane ikaranze ku bushyuhe buke. Ifite imikorere myinshi ya pozzolanic, ikoreshwa cyane nk'ubuvange bwa beto, kandi ishobora no gukoreshwa mu gukora polimeri za geologiya zikora neza cyane.
