Biriki ya aluminium ya zulu-kele mutindu ya kima yina ke pelaka ve tiya yina me salama ntete-ntete na oxide d’aluminium (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%), Kitini ya Zole (60-75%), mpi Kitini ya Tatu (48-60%).
Yau kele bima ya aluminiosilicate yina kefwaka ve tiya yina kele na oxide d’aluminium (Al2O3) kuluta 48%.
Yau kele mutindu ya bima ya kukonda tiya yina kele na alumine kuluta 48%, yina kesalamaka na kutungaka mpi na kuyokaka bauxite to bima yankaka ya ntete yina kele ti alumine mingi. Bo ke monisaka ngolo ya tiya mpi ngolo ya kuluta 1770 degrés . Sambu yo ke kangamaka mbote na ba slag, bo ke sadilaka yo sambu na kusala bafour ya kura yina ke salaka bibende, bafour ya kuyoka bima ya glase, mpi bafour ya ke balukaka na simente.
Babriki ya aluminium yina ke lembaka mingi, yina ke tambulaka fioti [1] kele bima ya kuluta mbote yina bo ke salaka ntete-ntete na bauxite ya sipesiali, na corundum yina bo me vukisaka, mpi na mullite yina bo me vukisaka. Babriki yai ke pesaka mambote bonso kutambula na zulu ya temperature ya fioti ya ngolo-, kukangama ngolo na erosion, mpi kukangama mbote na ba choc thermique.
Yau mefwana sambu na ba four ya tiya ya nene mpe ya kati-kati-, yau kemonisa kitambi ya mbote na yina metala kusala na kati ya insi bima ya tiya ya mbote, ya ngolo - yina bo vandaka kunata ntete na insi na munu sambu na bafour ya tiya ya mpa ya -ya mbandu ya insi na munu; kima yayi me kota na "Programe ya Spark" ya insi.
