He mea waiwai nui ka alumina superfine no nā seramika hana.ʻO ka pauka alumina superfine xz-L20, ka nui o ka ʻāpana 100 nm, waihoʻoluʻu keʻokeʻo, 99% o ka ʻike paʻa.Hiki ke hoʻohui ʻia i nā resins wai like ʻole, i loko o nā resins i hoʻokumu ʻia i ka aila, nā mea hoʻoheheʻe a me nā rubbers ma kahi pae hoʻohui o 3% -5%, hiki ke hoʻomaikaʻi nui i ka paʻakikī o ka mea a hiki i 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 maloʻo, a ʻaʻohe hana catalytic.Loaʻa iā ia ke kūpaʻa wela ikaika, ka formability maikaʻi, ka pae crystalline paʻa, ka paʻakikī kiʻekiʻe a me ka paʻa o ka dimensional maikaʻi, a hiki ke hoʻohana nui ʻia i ka hoʻoikaika ʻana a me ka paʻakikī o nā ʻano plastics, rubber, ceramics, refractory material a me nā huahana ʻē aʻe, ʻoi aku ka hoʻomaikaʻi ʻana i ka denseness, ka pau ʻana, ka luhi wela a me ke anu, ka paʻakikī haʻihaʻi, ke kūpaʻa ʻana o nā seramika a me ka pale ʻana o nā mea polymer.
