He rauemi pūwero te α-Al2O3, e whakamahia ana mō te tautoko i ngā whakakorikori, ngā mea mimiti, ngā rauemi wehewehe hau, me ētahi atu. Ko te α-Al2O3 te wāhanga tino pumau o ngā alumina katoa, ā, e whakamahia ana hei tautoko i ngā wāhanga hohe whakakorikori me te ōwehenga mahi teitei. He nui ake te rahi o ngā pūwero o te kaikawe whakakorikori α-Al2O3 i te ara kore utu ngota, ā, he ōrite te tohatoha, nō reira ka taea te whakakore pai ake i te raruraru horapa ā-roto i puta mai i te iti o ngā pūwero i roto i te pūnaha tauhohenga whakakorikori, ā, ka taea te whakaiti i ngā tauhohenga taha waikura hohonu i roto i te tukanga mō te kaupapa o te waikura whiriwhiri. Hei tauira, ko te whakakorikori hiriwa e whakamahia ana mō te waikura ethylene ki te waikura ethylene e whakamahi ana i te α-Al2O3 hei kaikawe. He maha te whakamahinga i roto i ngā tauhohenga whakakorikori me te pāmahana teitei me te whakahaere horapa o waho.
