Description	The mechanical properties of starch-zirconia composites, prepared by starch consolidation casting, and their as-fired counterparts (porous zirconia ceramics) are investigated. The elastic modulus and strength can be controlled by selecting the starch type and fine-tuned by applying starch mixtures. Rice starch enhances both the Young's modulus and the flexural strength. For bodies with 30 vol.% of starch, the bulk densities are 2.17-2.47 g/cm3. Young's moduli can attain values of up to 7 GPa, while flexural strengths attain values up to 12 MPa, with a close correlation to bulk density. After firing porous zirconia ceramics are obtained, in which the bulk density differences are retained, leading to total porosities of 34, 26 and 21 % when using 30 vol.% of potato, corn and rice starch, respectively. Young's moduli are of order 60-120 GPa. Irrespective of the starch type, they exhibit a strong correlation to porosity, which is best described by an exponential relation.
