Abstract
Porous zirconia ceramics are widely considered to be important due to their unique properties and potential applications. In this paper, we propose a novel approach to produce porous zirconia ceramics. The linear shrinkage of the prepared porous zirconia ceramics could be controlled to 4% by incorporating pre-sintered zirconia granules and hollow polymeric spheres. We also investigated the effect of pre-sintered zirconia granules on the microstructure and the properties, such as the porosity, pore distribution, and bending strength of the porous zirconia ceramics.
