I-Al2O 3 ne-MgO zengezwa ngesisekelo sesistimu ye-SiO 2-cao-na2o ternary, ehlukile kunengilazi yepuleti ngokuthi okuqukethwe kwe-Al2O 3 kuphakeme futhi okuqukethwe kwe-CaO kuphakeme, kuyilapho okuqukethwe kwe-MgO kuphansi.
Kungakhathaliseki ukuthi hlobo luni lwemishini yokubumba, kungakhathaliseki ukuthi amabhodlela kabhiya, amabhodlela otshwala, amathini angasetshenziswa lolu hlobo lwezithako, adinga kuphela ukwenza ukulungiswa okuhle ngokusho kwesimo sangempela. Ukwakheka kwayo (ingxenye enkulu) ububanzi yilokhu: SiO 27%~73%, A12O 32%~5%, CaO 7.5%~9.5%, MgO 1.5%~3%, R2O 13.5%~14.5%.
Lolu hlobo lwesithako lubonakala ngokuqukethwe kwe-aluminium okumaphakathi, ukusetshenziswa kwe-Al2O3 equkethe isihlabathi se-silica, noma ukwethulwa kwe-alkali metal oxides nge-feldspar ukuze ulondoloze izindleko. Inani le-CaO+MgO liphezulu uma kuqhathaniswa, futhi isivinini sokuqina siyashesha, ukuze uvumelane nesivinini somshini esiphezulu, ingxenye ye-MgO isetshenziswa esikhundleni se-CaO ukuvimbela ingilazi ukuthi ingacwebezeli emgodini wokugeleza kwamanzi, ukuphakela. umshini wokuhamba nowokudla. I-Al2O3 emaphakathi ingathuthukisa amandla emishini nokuzinza kwamakhemikhali engilazi.
