ʻO White Fused Alumina he mineral synthetic kiʻekiʻe.

Hana ʻia ia e ka hui ʻana o ka Bayer Alumina māka maʻemaʻe maikaʻi i hoʻopaʻa ʻia i loko o kahi umu ahi arc i nā mahana i ʻoi aku ma mua o 2000˚C a ukali ʻia e kahi kaʻina hana paʻa lohi.

ʻO ka mana koʻikoʻi ma luna o ka maikaʻi o nā mea maka a me nā ʻāpana fusion e hōʻoia i nā huahana o ka maʻemaʻe kiʻekiʻe a me ke keʻokeʻo kiʻekiʻe.

Hoʻopili hou ʻia ka ʻōpala maloʻo, hoʻomaʻemaʻe ʻia i nā haumia magnetic i nā mea hoʻokaʻawale magnetic ikaika a hoʻokaʻawale ʻia i loko o nā hakina liʻiliʻi e kūpono i ka hoʻohana hope.
