TODO - In this study we report the synthesis and characterization of ceramic beads of hierarchical porosity in the meso and macro pore range. The materials preparation is based on the combination of polymer templating and phase inversion methods. Three different kind of ceramic powders: α-alumina (α-Al2O3), yttria stabilized zirconia (YSZ) and apatite type lanthanum silicate oxide (LFSO) were used for the formation of mm monomodal sized beads. High total porosity values were found (40%-75%) depending on the material sintering properties and the preparation method. The pore size distribution revealed graded pores in the range of large meso and macro pore range depending on the thermal treatment of the materials.
