ʻO ka alumina (AL2O3), he mea paʻakikī a hoʻohana ʻia ma nā ʻoihana he nui.Ke puhi ʻia a hoʻopaʻa ʻia, hiki ke hana ʻia me ka hoʻohana ʻana i nā ʻano wili daimana.ʻO ka alumina ka mea maʻamau i hoʻohana pinepine ʻia a loaʻa i ka maʻemaʻe a hiki i 99.9%.ʻO kona hui pū ʻana o ka paʻakikī, ka hana wela kiʻekiʻe (a hiki i 1,700 ° C) a me ka insulation uila maikaʻi e pono ai ia no nā ʻano hana like ʻole.
Kokoke alumina maʻemaʻe (99.7%) hāʻawi i ka hana wela kiʻekiʻe loa no nā paipu pale.
