Ma ke kahua o ka ʻepekema mea, ke ʻimi mau nei mākou i nā mea hou me nā waiwai maikaʻi loa a me ke kūpaʻa. I waena o lākou, hoʻohana nui ʻia nā keramika alumina ma nā ʻano like ʻole ma muli o ko lākou mau waiwai kino a me ke kemika maikaʻi loa, a me ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa i ka pala. I kēia lā, e nānā pono kākou i ke kūpaʻa kemika o nā keramika alumina.
ʻO ka mea mua, ʻo ke kūpaʻa kemika onā keramika aluminaʻike nui ʻia i kona kūpaʻa ʻana i ka hapa nui o nā waikawa, nā kumu a me nā oxidants. ʻO kēia no ka mea ua paʻa ke ʻano o nā keramika alumina a ua ikaika ka pilina ma waena o nā molekala, ka mea e hiki ai iā ia ke mālama i kona ʻano mua a me nā waiwai i ka hapa nui o nā ʻano ʻino. ʻO kēia kūpaʻa e hoʻohana nui ʻia ai nā keramika alumina i nā kemika, petroleum, metallurgy a me nā ʻoihana ʻē aʻe.
ʻO ka lua, ʻike ʻia ke kūpaʻa kemika o nā keramika alumina i kona mau waiwai antioxidant. Ma lalo o nā kūlana wela kiʻekiʻe, e hana nā mea he nui me ka oxygen, e hoʻololi ai i ko lākou ʻano a me nā waiwai. Eia nō naʻe, noho paʻa nā keramika alumina i kēia kaiapuni a ʻaʻole hana me ka oxygen. ʻO kēia kūpaʻa oxidation e hoʻolilo i nā keramika alumina i mea nui i ka aerospace, ka pūʻali koa a me nā ʻoihana ʻē aʻe.
Eia kekahi, ʻike ʻia ke kūpaʻa kemika o nā keramika alumina i kona kūpaʻa ʻana i ka waikawa a me ka alkali. I ko kākou ola o kēlā me kēia lā, he mau mea maʻamau nā waikawa a me nā kumu, a he hopena corrosive ko lākou i nā mea he nui. Eia nō naʻe, hiki i nā keramika alumina ke kū'ē i ka waikawa a me ka alkali corrosion a mālama i ko lākou mau waiwai a me ke ʻano kumu. ʻO kēia kūpaʻa ʻana i ka waikawa a me ka alkali corrosion e hoʻohana nui ʻia ai nā keramika alumina i ka hana ʻana i ka meaʻai, kemika, ka lāʻau lapaʻau a me nā ʻoihana ʻē aʻe.
Ma keʻano laulā, paʻa nā waiwai kemika o nā keramika alumina, i hiki iā lākou ke mālama i ka hana maikaʻi a me ke ʻano ma nā ʻano ʻino like ʻole. ʻO kēia kūpaʻa e hoʻohana nui ʻia ai nā keramika alumina ma nā ʻano he nui.
