ʻO ka pauka poli alumini oxide i hoʻohana ʻia no ka poli ʻana i ka pena kaʻa
He mea maʻemaʻe kiʻekiʻe ka pauka alumina, he mea i hana ʻia mai ka alumini oxide (Al2O3) i hoʻohana nui ʻia i nā ʻano hana ʻoihana like ʻole. He pauka kristal keʻokeʻo ia i hana pinepine ʻia ma o ka hoʻomaʻemaʻe ʻana i ka ore bauxite.
He nui nā waiwai i makemake ʻia o ka pauka alumina, me ka paʻakikī kiʻekiʻe, ke kūpaʻa kemika, a me ka insulation uila, ka mea e lilo ai ia i mea waiwai nui ma nā ʻoihana he nui.
Hoʻohana pinepine ʻia ia ma ke ʻano he mea maka no ka hana ʻana i nā keramika, nā mea hoʻoheheʻe, a me nā mea abrasive, a no ka hana ʻana i nā ʻano ʻāpana uila like ʻole, e like me nā insulators, substrates, a me nā ʻāpana semiconductor.
Ma ke kahua lapaʻau, hoʻohana ʻia ka pauka alumina i ka hana ʻana o nā mea hoʻokomo niho a me nā mea hoʻokomo orthopedic ʻē aʻe ma muli o kona biocompatibility a me ke kūpaʻa ʻana i ka pala. Hoʻohana ʻia nō hoʻi ia ma ke ʻano he mea hoʻopili i ka hana ʻana o nā aniani optical a me nā ʻāpana kikoʻī ʻē aʻe.
Ma keʻano holoʻokoʻa, he mea maʻalahi ka pauka alumina i loaʻa ka hoʻohana nui ʻia ma nā ʻano hana ʻoihana like ʻole ma muli o kona hui kūikawā o nā waiwai kino a me nā kemika.

1.ʻOihana keramika:Hoʻohana nui ʻia ka pauka alumina ma ke ʻano he mea maka no ka hana ʻana i nā keramika, me nā keramika uila, nā keramika refractory, a me nā keramika ʻenehana holomua.
2.ʻOihana Hoʻopili a me ka ʻAbrasive:Hoʻohana ʻia ka pauka alumina ma ke ʻano he mea hoʻopili a me ka mea abrasive i nā hana like ʻole e like me nā aniani optical, nā wafers semiconductor, a me nā ʻili metala.
3.Hoʻouluulu:Hoʻohana ʻia ka pauka alumina ma ke ʻano he kākoʻo catalyst i ka ʻoihana petrochemical e hoʻomaikaʻi i ka pono o nā catalysts i hoʻohana ʻia i ke kaʻina hana hoʻomaʻemaʻe.
4.Nā Uhi ʻEleʻele Wela:Hoʻohana ʻia ka pauka alumina ma ke ʻano he mea uhi e hāʻawi i ke kūpaʻa i ka pala a me ke komo ʻana i nā ʻili like ʻole i nā ʻoihana aerospace a me nā ʻoihana kaʻa.
5.Palekana Uila:Hoʻohana ʻia ka pauka alumina ma ke ʻano he mea hoʻokaʻawale uila i nā mea uila ma muli o kona ikaika dielectric kiʻekiʻe.
6.ʻOihana Refractory:Hoʻohana ʻia ka pauka alumina ma ke ʻano he mea refractory i nā noi wela kiʻekiʻe, e like me nā uhi umu, ma muli o kona kiko heheʻe kiʻekiʻe a me ke kūpaʻa wela maikaʻi loa.
7.Mea hoʻohui i loko o nā Polymers:Hiki ke hoʻohana ʻia ka pauka alumina ma ke ʻano he mea hoʻohui i loko o nā polymers e hoʻomaikaʻi i ko lākou mau waiwai mechanical a me thermal.
