Wfa Keʻokeʻo i hoʻohui ʻia ʻo Alumina/Aluminum Oxide/Alumina Oxide/Corundum
Wehewehe Huahana
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.
