He maʻalahi ka mea hana o ka keramika alumina, ʻoi aku ka paʻakikī i ka ʻenehana hana ʻana, haʻahaʻa ke kumukūʻai, maikaʻi loa i ka paʻakikī a me ke kūpaʻa ʻana i ka ʻaʻahu. Hoʻohana nui ʻia ia i nā paipu keramika pale ʻaʻahu, nā kiwikā pale ʻaʻahu e like me nā mea uhi, a hiki ke hoʻopaʻa ʻia me nā studs a i ʻole e hoʻopili ʻia i ka paia o loko o nā lako hoʻokaʻawale e like me ka wili kū pololei ʻoihana, ka mea hoʻohuihui pauka a me ka cyclone, hiki ke hāʻawi i ka 10 mau manawa o ke kūpaʻa ʻaʻahu o ka ʻili o nā lako. I nā mea pale ʻaʻahu, hiki i ka māhele mākeke o nā mea alumina ke hiki i kahi 60% ~ 70%.
ʻO ke ʻano koʻikoʻi o ka mea seramika SiC ka pale ʻana i ka haʻalulu wela maikaʻi. Ma lalo o nā kūlana wela kiʻekiʻe, loaʻa i ka mea nā waiwai mechanical paʻa a hiki ke hoʻohana paʻa ʻia ma 1800 ℃ no ka manawa lōʻihi. ʻO ka lua o nā ʻano, hiki ke hoʻohana ʻia ka mea silicon carbide e hana i nā huahana nui me ka deformation liʻiliʻi. Hoʻohana nui ʻia ia i ka ʻāpana kau preheater o ka ʻoihana sima, ka nozzle seramika pale wela kiʻekiʻe, ka paipu hāʻule lanahu a me ka paipu lawe wela kiʻekiʻe o ka ʻoihana mana wela. No ka laʻana, ʻo nā nozzles o nā mea puhi i nā mea kanu mana wela ua hana ʻia me ka silicon carbide, a loaʻa i nā huahana nā ʻano o ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa ʻana. ʻO nā ʻano sintering o nā seramika silicon carbide e pili ana i ka sintering reaction a me ka sintering pressureless. He haʻahaʻa ke kumukūʻai o ka sintering reaction, he ʻano ʻino nā huahana, a he kiʻekiʻe ke kiʻekiʻe o ka density o nā huahana sintering vacuum pressureless. Ua like ka paʻakikī o nā huahana me nā huahana alumina, akā ʻoi aku ke kiʻekiʻe o kona kumukūʻai.
ʻOi aku ka maikaʻi o ke kū'ē ʻana o nā mea keramika zirconia ma mua o nā mea palupalu. ʻO ke kumukūʻai mākeke o kēia manawa o ka pauka zirconia he pipiʻi loa, kahi i hoʻohana nui ʻia i nā kahua kiʻekiʻe, e like me nā mea niho, nā iwi hana, nā mea lapaʻau, a pēlā aku.
