Abstract
Highly interconnected porous yttria stabilised zirconia ceramics were prepared by slurry infiltration of expanded polystyrene powder compacts, followed by sintering at 1500°C. The porous zirconia ceramics exhibited a high porosity (60%) with uniform or graded pore sizes ranging from 300 um to 1000 μm. The compressive strength of the uniform porous ceramics decreased with the increase of pore size, whereas the compressive strength of the graded porous ceramics was anisotropic, depending on the direction of measurement. Compressive strengths from 8 MPa to 36 MPa were obtained for the porous zirconia ceramics.
