ʻO ka wehewehe pōkole:

ʻO ka Gamma alumina kahi pauka fluffy keʻokeʻo me ka hoʻohele like ʻana i ka nui o nā ʻāpana, ka maʻemaʻe kiʻekiʻe, a me ka hoʻopuehu maikaʻi. He kiʻekiʻe kikoʻī ili, kiʻekiʻe wela inertness, a me ka hana kiʻekiʻe. He alumina i ho'ā 'ia; porous; paʻakikī kiʻekiʻe a me ke kūpaʻa dimensional maikaʻi. Hiki ke hoʻohana nui ʻia i ka hoʻoikaika ʻana a me ka paʻakikī o nā plastics like ʻole, rubbers, ceramics, refractory material a me nā huahana ʻē aʻe, ʻoi aku ka maikaʻi o ka hoʻomaikaʻi ʻana i ka compactness, smoothness, ke anu a me ka wela wela ke kū ʻana, fracture toughness, creep resistance a me nā huahana polymer kiʻekiʻe o nā seramika. . He mea kupaianaha loa ka pale ʻaʻahu.
