    I-Aluminium oxide (Al2O3)iwuketshezi olumhlophe noma olucishe lungabi nambala, kanye nenhlanganisela yamakhemikhali e-aluminium nomoya-mpilo. Yenziwe nge-bauxite futhi evame ukubizwa nge-alumina futhi ingase futhi ibizwe nge-aloxide, i-aloxite, noma i-alundum kuye ngamafomu athile noma izinhlelo zokusebenza. I-Al2O3 ibalulekile ekusetshenzisweni kwayo ukukhiqiza insimbi ye-aluminium, njenge-abrasive ngenxa yokuqina kwayo, futhi njengento ephikisayo ngenxa yezinga layo eliphezulu lokuncibilika.
