Porous ceramicsyog ib pab pawg ntawm cov ntaub ntawv ceramic uas muaj peev xwm ua tau ntau yam qauv, nrog rau cov foams, honeycombs, txuas rods, fibers, hollow spheres, los yog interconnecting rods thiab fibers.

Porous ceramicsyog categorized li cov uas muaj feem pua siab ntawm porosity, nruab nrab ntawm 20% thiab 95%. Cov ntaub ntawv no yog tsim los ntawm tsawg kawg yog ob theem, zoo li cov khoom ceramic theem thiab cov pa roj-filled porous theem. Vim muaj peev xwm pauv roj nrog ib puag ncig los ntawm cov pore channel, cov roj cov ntsiab lus ntawm cov pores no feem ntau hloov mus rau ib puag ncig. Kaw qhov pores yuav tuav cov roj muaj pes tsawg leeg uas tsis muaj kev ywj pheej ntawm qhov chaw nyob ib puag ncig. Txhua lub cev lub cev porosity tuaj yeem muab faib ua ntau pawg, suav nrog qhib (muaj los ntawm sab nraud) porosity thiab kaw porosity. Qhib qhov pores kawg thiab qhib qhov pore channel yog ob hom kev qhib porosity. Ib qho qhib porosity yuav tsum tau ua kom permeable, tsis zoo li lub porosity kaw, los yog lim los yog daim nyias nyias, xws li thermal insulators, tej zaum yuav xav tau. Lub hav zoov ntawm porosity nyob ntawm daim ntawv thov tshwj xeeb.

Cov khoom ntawm porous ceramics tuaj yeem cuam tshuam zoo heev los ntawm kev hloov pauv hauv qhov qhib thiab kaw porosity, pore loj faib, thiab pore zoo. Porous ceramics 'cov yam ntxwv ntawm cov qauv, xws li qib ntawm porosity, pore loj, thiab daim ntawv, txiav txim siab lawv cov khoom siv tshuab.
