Pauka ʻokikene alumini keʻokeʻo WFA
Hana ʻia ka pauka alumina keʻokeʻo i hoʻohui ʻia me ka pauka alumina sodium haʻahaʻa kiʻekiʻe ma ka hoʻoheheʻe ʻana i ka mahana kiʻekiʻe, ka hoʻomaʻalili ʻana i ka crystallization, a laila ka wāwahi ʻana. Aia ka pauka alumini oxide keʻokeʻo i hoʻohui ʻia ma lalo o ka kaohi paʻa e mālama i ka hoʻolaha ʻana o ka nui o ka palaoa a me ke ʻano like.
He haiki ka hoʻolaha ʻana o ka nui o nā hua o ka pauka alumina keʻokeʻo i hoʻohui ʻia. Ma hope o ke kaʻina hana hoʻopili ʻana, he hua piha ka pauka corundum keʻokeʻo maʻemaʻe, ʻoi nā kihi a me nā kihi, kiʻekiʻe ka pono o ka wili ʻana, a me ka ʻōlinolino kiʻekiʻe. ʻOi aku ka kiʻekiʻe o ka pono o ka wili ʻana ma mua o nā mea abrasives palupalu e like me ka silica.
Ma muli o ke ʻano maikaʻi, he kiʻekiʻe ke ʻano o ka ʻili o ka mea i wili ʻia. Hoʻohana nui ʻia i ka wili ʻana a me ka wili ʻana o nā semiconductors, nā kristal, nā papa kaapuni, ka alumini, ke kila, ke kila kila, ka pōhaku, ke aniani, a pēlā aku. ʻOi loa aku hoʻi i ka ʻoihana o ka wili ʻana a me ka wili ʻana o ke kila kila, ka alumini, ke keleawe a me nā mea metala ʻē aʻe a me ka ʻoihana aniani, hōʻike piha ia i ka hana maikaʻi loa.
Pauka Alumina i hoʻohuihui ʻia keʻokeʻo
Keʻokeʻo, kristal α ma luna o 99%, maʻemaʻe kiʻekiʻe, paʻakikī kiʻekiʻe, a me ka paʻakikī kiʻekiʻe, ikaika ʻoki, kūpaʻa kemika ikaika, a me ka pale ikaika.

ʻAʻohe mea e pili ana i ke kala o nā ʻāpana i hana ʻia.
02
Hiki ke hoʻohana ʻia i nā kaʻina hana kahi i pāpā loa ʻia ai ke koena pauka hao.

He kūpono loa ke hoʻoponopono ʻana i nā ʻano hua no ka hoʻopāpā ʻana i ke one pulu a me nā hana wili.
1. Ke one ʻana, ka hoʻowali ʻana a me ka wili ʻana i ka metala a me ke aniani.
2. Hoʻopiha ʻana i ka pena, ka uhi pale ʻaʻahu, ka seramika, a me ka glaze.
3. Hana ʻana i ka pōhaku ʻaila, ka pōhaku wili, ka huila wili, ka pepa one a me ka lole emery.
