ʻO ka keramika huʻa kahi ʻano keramika porous e like me ka huʻa i ke ʻano, a ʻo ia ke kolu o ka hanauna o nā huahana keramika porous i hoʻomohala ʻia ma hope o nā keramika porous maʻamau a me nā keramika porous honeycomb. Loaʻa i kēia keramika ʻenehana kiʻekiʻe nā pores i hoʻopili ʻia ʻekolu-dimensional, a hiki ke hoʻoponopono kūpono ʻia kona ʻano, ka nui o ka pore, ka permeability, ka ʻili a me nā waiwai kemika, a ua like nā huahana me ka "toughened foam" a i ʻole "porcelain sponge". Ma ke ʻano he ʻano hou o ka mea kānana non-metallic inorganic, loaʻa i ka keramika huʻa nā pono o ke kaumaha māmā, ka ikaika kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa i ka corrosion, ka hana hou maʻalahi, ke ola lawelawe lōʻihi a me ka kānana maikaʻi a me ka adsorption.
Hana mākou i ʻekolu mau mea hana,ʻO ke alumina, ka silicon carbide a me ka zirconia.
ʻIkepili loea e like me lalo nei
