I-calcium aluminate, njengento ebalulekile, inezinhlobonhlobo zezinhlelo zokusebenza, ngakho ukuncibilikisa umlotha we-aluminium ube yi-calcium aluminate nakho kunokubaluleka kwezomnotho nezimboni. Ukwelashwa okuhambisanayo nokulungiswa kuyadingeka kumlotha ohlukile we-aluminium ngesikhathi senqubo yokuncibilikisa. Okwesibili, phakathi nenqubo yokuncibilikisa, kuyadingeka ukulawula imingcele efana nezimo zokushisa nezimo zokusabela ukuze kuqinisekiswe ukuqhubeka kahle kokusabela nokuzinza kwekhwalithi yomkhiqizo. Ukuncibilikisa umlotha we-aluminium ube yi-calcium aluminate kuyindlela ephumelelayo yokwelashwa komlotha we-aluminium, engafinyelela ukutholwa kwensiza futhi isetshenziswe kabusha, futhi kunciphise ukungcoliswa kwemvelo. Sikholelwa ukuthi ubuchwepheshe bokuncibilikisa umlotha we-aluminium ube yi-calcium aluminate buzoba yinkimbinkimbi, bube negalelo elikhulu ekuthuthukisweni okusimeme kanye nokuvikelwa kwemvelo kwamabhizinisi e-aluminium.
Inqubo entsha yokuncibilikisa kanye nemishini eyakhiwe i-Xiye ingaphatha udoti oqinile womlotha we-aluminium ophuma esitshalweni se-aluminium, ikhiphe isici se-aluminium emlotheni, bese okunye ukungcola kube yi-calcium aluminate, uhlobo lwe-deoxidizer yokwenza insimbi, ngemva kokuncibilika. Ukuguqula imfucuza ibe umcebo, kulwa kakhulu nokungcoliswa kwemvelo futhi kuthuthukisa izinzuzo zezomnotho.
