    Aluminum Oxide (Al2O3)he keʻokeʻo a ʻaneʻane kala ʻole ʻole, a he hui kemika o ka alumini a me ka oxygen. Hana ʻia ia mai ka bauxite a kapa ʻia ʻo alumina a hiki ke kapa ʻia ʻo aloxide, aloxite, a i ʻole alundum ma muli o nā ʻano a i ʻole nā ​​noi. He mea koʻikoʻi ka Al2O3 i kona hoʻohana ʻana e hana i ka metala alumini, ma ke ʻano he abrasive no ka paʻakikī, a ma ke ʻano he mea refractory no kona wahi heheʻe kiʻekiʻe.
