Aluminom oxide alfa-phase 99.999% (ihe ndabere ọla)
Aluminom oxide (Al2O3)bụ ihe na-acha ọcha ma ọ bụ ihe fọrọ nke nta ka ọ bụrụ nke na-enweghị ụcha, yana ngwakọta kemịkalụ nke aluminom na oxygen. Emere ya site na bauxite na nke a na-akpọkarị alumina ma nwee ike ịkpọ ya aloxide, aloxite, ma ọ bụ alundum dabere na ụdị ma ọ bụ ngwa. Al2O3 dị ịrịba ama na iji ya na-emepụta ọla aluminom, dị ka abrasive n'ihi ike ya, yana dị ka ihe mgbagha n'ihi nnukwu agbaze ya.
