Hana ʻia ʻo Brown Fused Alumina e ka hoʻoheheʻe ʻia ʻana o Calcined Bauxite i loko o ka umu ahi arc i nā mahana ʻoi aku ma mua o 2000°C. ʻO kahi kaʻina hoʻopaʻa paʻa lohi e hahai i ka hui ʻana, e hāʻawi i nā kristal blocky. ʻO ke kōkua o ka hoʻoheheʻe ʻana i ke koena o ka sulfur a me ke kalapona, ʻo ka hoʻomalu koʻikoʻi ma luna o nā pae Titania i ka wā o ka hui ʻana e hōʻoia i ka paʻakikī o ka ʻai.

A laila e ʻoki 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. Hoʻopuka nā laina hoʻolaʻa i nā huahana no nā noi like ʻole.

ʻO Brown Fused Alumina he mea paʻakikī, ʻoi aku ka maikaʻi no ka wili ʻana i nā metala o ka ikaika tensile kiʻekiʻe. ʻO kāna mau mea wela e lilo ia i mea maikaʻi loa no ka hoʻohana ʻana i ka hana ʻana i nā huahana refractory. Hoʻohana ʻia kēia mea i nā noi ʻē aʻe e like me ka pahū a me ka paʻakikī o ka ʻili.
