Sharaxaada
Leben alumina sare waa nooc ka mid ah refractory, qaybta ugu weyn ee taas oo ah Al2O3. Haddii nuxurka Al2O3 uu ka sarreeyo 90%, waxaa loo yaqaan leben corundum. Sababo la xiriira kheyraadka kala duwan, halbeegyada wadamo kala duwani ma aha kuwo si buuxda u siman. Tusaale ahaan, wadamada Yurub, xadka hoose ee Al2O3 ee loogu talagalay soo-celinta aluminiumka sare waa 42%. Shiinaha, waxyaabaha Al2O3 ee leben aluminium sare ah ayaa guud ahaan loo qaybiyaa saddex darajo: Fasalka I - Al2O3 content> 75%; fasalka II - Al2O3 waxa ku jira waa 60-75%; fasalka III - Al2O3 waxa ku jira waa 48-60%.

Codsiga:
Lebenka sare ee aluminiumka ah ayaa si caan ah loo isticmaalaa dhismooyinka dhogorta gudaha ee warshadaha, sida foornooyinka qaraxa, foornooyinka kulul ee kulul, foornada korontada ku jirta, reverberator, foornada sibidhka wareega iyo wixii la mid ah. Ka sokow, lebenka aluminium sare ayaa sidoo kale si ballaaran loo isticmaalaa sida leben hubinta dib-u-cusbooneysiinta, joojinta nidaamka shubista joogtada ah, lebenka dulinka, iwm.
