ʻO ka ʻokoʻa ma waena o ka corundum brown a me keʻokeʻo

1. Nā mea maka like ʻole: ʻo ka mea maka o ka corundum ʻeleʻele he bauxite, me ka anthracite a me nā waihona hao. ʻO ka mea maka o ka corundum keʻokeʻo he pauka alumini oxide.
2. Nā waiwai like ʻole: he ʻano maʻemaʻe kiʻekiʻe ko ka corundum ʻeleʻele, crystallization maikaʻi, fluidity ikaika, coefficient haʻahaʻa o ka hoʻonui linear, kū'ē i ka corrosion. Loaʻa i ka corundum keʻokeʻo nā ʻano maʻemaʻe kiʻekiʻe, hoʻokala ponoʻī maikaʻi, kū'ē i ka waikawa a me ka alkali corrosion, kū'ē i ke ana wela kiʻekiʻe a me ka hana wela paʻa. I ka hoʻohālikelike ʻana, ʻoi aku ka paʻakikī o ka corundum keʻokeʻo ma mua o ka corundum ʻeleʻele.
3. Nā mea hoʻohui like ʻole: ʻoiai aia ka alumina i loko o ka corundum ʻeleʻele a me ke keʻokeʻo, kiʻekiʻe ka alumina i loko o ka corundum keʻokeʻo,
4. Nā kala like ʻole: No ka mea, ʻoi aku ka nui o ka alumina o ka corundum keʻokeʻo ma mua o ka corundum ʻeleʻele, he keʻokeʻo ke kala o ka corundum keʻokeʻo, a he ʻeleʻele ʻeleʻele ka corundum ʻeleʻele.
5. Hana like ʻole: hana ʻia ka corundum keʻokeʻo me ka pauka alumina (ʻo ia ka mea maka like me ka alumini electrolytic), ʻoiai ʻo ka corundum ʻeleʻele i hana ʻia me ka bauxite calcined.
6. Loaʻa i ka corundum keʻokeʻo ka ikaika ʻokiʻoki, hoʻohana ʻia e wehe i ka burr metala a i ʻole ka burr metala ʻole, ka burr mua batch, a pēlā aku. Loaʻa iā ia ka hana o ka polishing ʻāpana ʻili, corundum ʻeleʻele i hoʻohana ʻia e wehe i ke kila kila, ke kila kalapona, ka alumini metala a me nā ʻāpana lako ʻē aʻe burr ʻili
7. Ka hoʻohana ʻana i nā mea like ʻole: hoʻohana ʻia ka corundum keʻokeʻo e kekahi poʻe hoʻohana kiʻekiʻe, no ka mea, ʻoi aku ka maikaʻi o ka ʻoki ʻana, maikaʻi loa ka hopena polishing, hoʻohana nui ʻia no ke kila kalapona, ke kila alloy, ka hao malleable, ke keleawe paʻakikī a pēlā aku, a hoʻohana nui ʻia ka corundum ʻeleʻele ma ka mākeke, akā nui nō hoʻi ka nui o ka mākeke, hoʻohana nui ʻia no ke kila ahi, ke kila wikiwiki, ke kila kalapona kiʻekiʻe a pēlā aku.
He ikaika ka ʻoki ʻana o ka corundum keʻokeʻo, hoʻohana ʻia e wehe i ka burr metala a i ʻole non-metal, batch front burr, a pēlā aku. Loaʻa iā ia ka hana o ka hoʻopili ʻana i nā ʻāpana o ka ʻili, hoʻohana ʻia ka corundum ʻeleʻele e wehe i ke kila kila, ke kila kalapona, ka alumini me nā ʻāpana lako ʻē aʻe. ʻAʻole wili ka corundum ʻeleʻele e like me ka maikaʻi a me ka ʻālohilohi e like me ka corundum keʻokeʻo.
