He mea maʻalahi ka alumina ceramic i ka waiwai, oo i ka ʻenehana hana, haʻahaʻa haʻahaʻa i ke kumu kūʻai, maikaʻi loa i ka paʻakikī a me ke kūpaʻa ʻana. Hoʻohana nui ʻia ia i nā paipu seramika paʻa paʻa, nā kīwī kūʻokoʻa e like me nā mea lining, a hiki ke hoʻopaʻa ʻia me nā studs a i hoʻopaʻa ʻia i ka paia o loko o nā mea hoʻokaʻawale e like me ka wili kūloko ʻoihana, concentrator pauka a me cyclone, hiki ke hāʻawi i 10 manawa e komo i ke kū'ē i ka ʻili o nā mea hana. I nā mea pale lole, hiki i ka mākeke o nā mea alumina ke hiki i kahi 60% ~ 70%.
ʻO ka hiʻohiʻona koʻikoʻi o nā mea seramika SiC ʻo ke kūpaʻa haʻalulu wela maikaʻi. Ma lalo o nā kūlana wela kiʻekiʻe, ua paʻa nā waiwai mechanical a hiki ke hoʻohana paʻa ʻia ma 1800 ℃ no ka manawa lōʻihi. ʻO ka lua o ka hiʻohiʻona ʻo ia ka mea hiki ke hoʻohana ʻia ka silicon carbide e hana i nā huahana nui me ka liʻiliʻi deformation. Hoʻohana nui ʻia ia i ka preheater e kau ana ʻāpana o ka ʻoihana sima, kiʻekiʻe wela aahu-kū kū'ē ceramic nozzle, lanahu hāʻule paipu a kiʻekiʻe-mehana hoʻoili paipu o ka thermal mana oihana. No ka laʻana, ʻo nā nozzles o nā mea puhi ahi i nā mea kanu wela i hana maoli ʻia me ka silicon carbide, a loaʻa i nā huahana nā hiʻohiʻona o ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa ʻaʻahu. ʻO nā ʻano sintering o nā seramika silicon carbide e komo pū me ka sintering reaction a me ka sintering pressureless. He haʻahaʻa ke kumukūʻai o ka sintering reaction, ʻano ʻino nā huahana, a he kiʻekiʻe ke kiʻekiʻe o nā huahana sintering ʻaʻohe pressureless. ʻO ka paʻakikī o nā huahana e like me nā huahana alumina, akā ʻoi aku ka kiʻekiʻe o kona kumukūʻai.
ʻOi aku ka maikaʻi o ka pale ʻana o nā mea seramika zirconia ma mua o nā mea brittle. ʻO ke kumukūʻai kūʻai o kēia manawa o ka pauka zirconia he mea kūʻai nui, ka mea i hoʻohana nui ʻia i nā kula kiʻekiʻe, e like me nā mea niho, iwi artificial, nā mea lapaʻau, etc.
