Keʻokeʻo huila alumina

Hana ʻia ka corundum keʻokeʻo ma lalo o nā kūlana wela ma luna o 2000 degere.Ma o nā kaʻina hana he nui e like me ka ʻoki ʻana, ka hoʻohua ʻana a me ke kānana ʻana, ʻoi aku ka maikaʻi ma ka helehelena a me ka paʻakikī ma ke ʻano he mea hoʻohana nui ʻia.ʻAʻole kiʻekiʻe wale ka corundum keʻokeʻo i ka paʻakikī, akā he brittle hoʻi i ke ʻano, ikaika i ka mana ʻoki.He hana maikaʻi nō hoʻi ia i ka insulation, ka hoʻomaʻamaʻa ponoʻī, ka pale ʻana a me ka conductivity thermal.I kēia manawa, kū'ē ia i kaʻakika a me ka alkali corrosion a me ka wela kiʻekiʻe.No laila, ma ke ʻano he mea paʻakikī loa, loaʻa i ka corundum keʻokeʻo nā waiwai maikaʻi loa.
