Developing porous ceramics on the base of zirconia oxide with thin and permeable pores by crystallization of organic additive method

Abstract

In this paper porous ceramics on the base of ZrO₂ nanopowders and micropowders has been developed by freeze-casting method. A zirconia/carbamide slurry was frozen in mold and dehydrated in CaCl₂ at room temperature. This simple process enabled the formation of porous ceramics with highly aligned pores as a replica of the carbamide crystals. The samples showed higher porosity of 47.9%. In addition, these materials could be used as membrane for air cleaning.
