Ma ke ʻano o ka nui a me ka ʻike alumini oxide maʻemaʻe, ʻo ka alumini oxide ceramic ka mea maʻamau maʻamau. ʻO ka alumini oxide, ka mea i kapa ʻia ʻo Alumina, ʻo ia ka keramika mua i nānā ʻia e ka mea hoʻolālā inā e noʻonoʻo ana ʻo ia e hoʻohana i nā seramika e pani ai i nā metala a i ʻole hiki ke hoʻohana ʻia nā metala ma muli o ke kiʻekiʻe o ka wela, nā kemika, ka uila, a i ʻole ka lole. ʻAʻole kiʻekiʻe loa ke kumukūʻai o ka mea ma hope o ka puhi ʻia ʻana, akā inā makemake ʻia ka ʻae ʻana, pono ka wili daimana a me ka polishing, hiki ke hoʻohui i nā kumukūʻai he nui a ʻoi aku ka maikaʻi o ka ʻāpana ma mua o kahi ʻāpana metala. Hiki ke mālama ʻia mai kahi pōʻai ola lōʻihi a i ʻole ka manawa liʻiliʻi e lawe ʻia ka ʻōnaehana ma waho e hoʻopaʻa ʻia a hoʻololi ʻia paha. ʻOiaʻiʻo, ʻaʻole hiki ke hana i kekahi mau hoʻolālā inā hilinaʻi lākou i nā metala ma muli o ke kaiapuni a i ʻole nā ​​koi o ka noi.

ʻOi aku ka haki ʻana o nā seramika a pau ma mua o ka hapa nui o nā metala, ʻo ia ka mea e noʻonoʻo ai ka mea hoʻolālā. Inā ʻike ʻoe he maʻalahi ʻo Alumina e ʻoki a wāwahi paha i kāu noi, ʻo Zirconium oxide ceramic, i ʻike ʻia ʻo Zirconia, he koho maikaʻi loa ia e nānā ai. He paʻakikī loa a kūpaʻa i ka ʻaʻahu. He ikaika loa ʻo Zirconia ma muli o kona ʻano ʻano kristal tetragonal kū hoʻokahi, i hui pū ʻia me Yttria. ʻO nā hua liʻiliʻi o Zirconia e hiki ai i nā mea hana ke hana i nā kikoʻī liʻiliʻi a me nā ʻaoʻao ʻoi e hiki ke kū i ka hoʻohana ʻino.

Ua ʻae ʻia kēia mau mea maka no kekahi mau lāʻau lapaʻau a i loko o ke kino a me nā hoʻohana ʻoihana he nui. ʻO nā mea hoʻolālā o nā ʻāpana seramika no ka hoʻohana ʻana i ka lāʻau lapaʻau, aerospace, semiconductor, instrumentation, a me nā noi ʻoihana makemake i kā mākou ʻike i ka hana pololei.
