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

Research output: Contribution to journal › Article

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.
