Amabaati aga waggulu-alumina kika kya kintu ekiziyiza omuliro okusinga nga kikolebwa aluminiyamu okisayidi (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%), Ekibiina II (60–75%), n’Ekibiina III (48–60%).
Zino bikozesebwa ebiziyiza aluminosilicate nga birimu aluminiyamu okisayidi (Al2O3) ebisukka mu 48%.
Zino kika kya kintu ekitaliimu buzibu nga kirimu alumina asukka mu 48%, nga zikolebwa nga zibumba n’okuzisiiga bauxite oba ebintu ebirala ebisookerwako ebirimu alumina. Ziraga obutebenkevu obw'ebbugumu obw'amaanyi n'obuziyiza obusukka mu diguli 1770 . Olw’okuba zigumira bulungi slag, zikozesebwa okukola layini mu kyokero ky’ebyuma eby’amasannyalaze, ebikoomi ebisaanuusa endabirwamu, n’ebikoomi ebizitowa seminti.
Amabaati ga alumina agasinga-omugugu-agogonza, aga wansi-agaseeyeeya waggulu-alumina [1] bintu bya mutindo gwa waggulu ebiziyiza omuliro ebikolebwa okusinga okuva mu bauxite ey’enjawulo-grade, fused corundum, ne fused mullite. Amabaati gano gawa ebirungi nga okuseeyeeya okw’ebbugumu eringi-li wansi, okuziyiza okw’amaanyi okukulugguka kw’ettaka, n’okunywerera obulungi ennyo mu kuwuuma kw’ebbugumu.
Esaanira sitoovu ennene n’eza wakati{0}}ez’obunene, zikiikirira eddaala obuwanguzi erigenda mu kukola ebintu eby’omutindo ogwa waggulu-eby’omutindo ogwa waggulu-eby’omutindo ogwa waggulu-ebiyingizibwa emabegako okukola sitoovu ez’omulembe omupya-ez’eggwanga lyange; ekintu kino kibadde kiyingiziddwa mu "Spark Program" y'eggwanga.
