ʻO ka mahana hana a me ka hoʻopili ʻana o nā piliki ahi māmā maʻamau 2

3. Piliki poepoe hollow Alumina

ʻO kāna mau mea maka nui he mau pōpō alumina hollow a me ka pauka alumini oxide, i hui pū ʻia me nā mea hoʻopaʻa ʻē aʻe. A ua puhi ʻia i ka mahana kiʻekiʻe o 1750 degere Celsius. No nā mea mālama ikehu a me nā mea hoʻokaʻawale wela kiʻekiʻe loa ia.
He paʻa loa ia e hoʻohana ai i nā lewa like ʻole. Kūpono loa no nā noi i loko o nā umu wela kiʻekiʻe ma 1800 ℃. Hiki ke hoʻohana ʻia nā pōpō hakahaka e like me ke kiʻekiʻe o ka mahana a me ka ultra-kiʻekiʻe.nā mea hoʻopihapiha hoʻomehana mahana, nā ʻākoakoa māmā no ka sima refractory wela kiʻekiʻe, ka hoʻoheheʻe wela kiʻekiʻe, a pēlā aku. Ma muli o nā ʻōkuhi kino a me nā kemika, hoʻohana nui ʻia nā piliki poepoe hollow alumini i nā umu wela kiʻekiʻe a me nā umu wela kiʻekiʻe loa e like me nā gasifiers ʻoihana petrochemical, nā umu hana ʻeleʻele kalapona, nā umu hoʻokomo ʻoihana metallurgical, a pēlā aku, a ua hoʻokō i nā hopena mālama ikehu maikaʻi loa.
