He mea koʻikoʻi ka alumina maikaʻi loa no nā keramika hana. ʻO ka pauka alumina maikaʻi loa xz-L20, ka nui o ka ʻāpana 100 nm, keʻokeʻo ke kala, 99% o ka ʻike paʻa. Hiki ke hoʻohui ʻia i nā resins wai like ʻole, i loko o nā resins aila, nā mea hoʻoheheʻe a me nā ʻōpala ma kahi pae hoʻohui o 3%-5%, hiki ke hoʻomaikaʻi nui i ka paʻakikī o ka mea a hiki i ka 6-8H a ʻoi aku paha.
ʻO ka palaoa Q-A1203, me kona ʻili kemika haʻahaʻa a me ke kūpaʻa wela kiʻekiʻe, ʻaʻole ia he alumina maloʻo i hoʻoulu ʻia, a ʻaʻohe ona hana catalytic. Loaʻa iā ia ke kūpaʻa wela ikaika, ka maikaʻi o ke ʻano, ka pae crystalline paʻa, ka paʻakikī kiʻekiʻe a me ke kūpaʻa dimensional maikaʻi, a hiki ke hoʻohana nui ʻia i ka hoʻoikaika a me ka hoʻoikaika ʻana o nā ʻano plastics like ʻole, rubber, ceramics, nā mea refractory a me nā huahana ʻē aʻe, ʻoi aku hoʻi e hoʻomaikaʻi i ka mānoanoa, ka hoʻopau ʻana, ka luhi wela a me ke anu, ka paʻakikī haki, ke kūpaʻa kolo o nā ceramics a me ke kūpaʻa ʻana o nā mea polymer.
