'''Alumina''' [[aluminio]] [[Oxido|oxidoa da]] (Al <sub>2</sub> O <sub>3</sub> ). [[Silizio dioxido|Silizea]] eta alumina dira [[buztin]] eta [[Esmalte|esmalteen]] osagai garrantzitsuenak.
 
Aluminio industria primarioak, aluminioa sortzeko aluminia erabiltzen du oinarrizko [[Lehengai|lehengaia]] modura.
