Properties of Microstructure‐Controllable Porous Yttria‐Stabilized Ziroconia Ceramics Fabricated by Freeze Casting
Source abstract
Abstract
Porous yttria‐stabilized ziroconia (YSZ) ceramics were fabricated by freeze casting using aqueous ceramic slurries. Polyvinyl alcohol (PVA) was added to the slurry with the aim of controling the microstructures and properties of the porous YSZ ceramics. The experimental results indicated that the large and noninterconnected lamellar pores of YSZ ceramics without PVA transformed changed into small and interconnected lamellar pores with PVA addition. The porosities of YSZ ceramics with PVA addition were higher than those of YSZ ceramics without PVA addition. The compressive strength of porous YSZ ceramics is the range from 23.57 to 63.86 MPa. All specimens exhibit noncatastrophic failure behaviors.
