Intandala sha aluminiamu ishikulu ni musango wa fipe ifishingapya ifyapangwa na aluminiamu (Al2O3).
Bricks with an Al₂O₃ content exceeding 90% are classified as corundum bricks. Standards vary by country due to differences in available resources; for instance, European standards set the minimum Al₂O₃ content for high-alumina refractories at 42%. In China, high-alumina bricks are typically categorized into three grades based on Al₂O₃ content: Grade I (>75%), Iciputulwa ca bubili (60-75%), na Iciputulwa ca butatu (48-60%).
Ici cipe ca aluminiamu icakwata umulilo wa aluminiamu (Al2O3) ukucila pali 48%.
Ni musango wa fipe ifishakwata umulilo ifyakwata umulilo ukucila pali 48%, ifipangwa ukupitila mu kupanga no kupanga umulilo nelyo ifipe fimbi ifyakwata umulilo uwafulilako. Balalanga ukushipikisha kwakulisha ukwa kukaba no kukanacimfya ukucila pa madigiri 1770 . Pa mulandu wa kuti balacingililwa bwino ku slag, balabomfya ku kupanga ifipe fya kupangapo ifipe ifya maka, ifipe fya kusungulula amagalasi, ne fipe fya kupangapo ifipe ifya simenti.
Amabumba ya alumina ayakulisha, ayacepako aya alumina [1] ni fipe fya mutengo ifyapangwa ukufuma ku bauxite iya pa lwakwe, corundum iyasankanishiwa, na mullite iyasankanishiwa. Aya matabwa yalapeela ifisuma pamo nga ukucepa kwa mucinshi uukalamba-ukutenkana kwa mushili, ukukaana kwa maka ukwa kuonaula, no kukanakwata amaka aya kukansana kwa mushili.
Icisuma ku fitofu ifikulu ne fya pa kati-ifyakufuuta ifya koca, fimininako intanshi ya kutunguluka iya kupanga ifya mu calo ifya pa muulu-ifya mutengo, ifya pa muulu-ifyakubomfya ifyakufuuta ifyalefuma kale ku fitofu fyakufuuta ifya koca ifya nkulo ipya-ifya calo candi; ici cipe cabikwa muli "Iciputulwa ca Spark" ica calo conse.
