Abstract The pore diameter, type (open or closed), physical properties of Porous alumina ceramic were controlled by varying concentration in the mixture of Polymethylmethacrylate (PMMA) with alumina powder and sintering temperature. The porous alumina ceramic was synthesis by a dry pressing method using a microspheres Polymethylmethacrylate (PMMA) as a pore-forming agent. The properties of the porous alumina were predicted using an experimental approach. Afterwards, the measured data were used to develop a Reduced-order model (Kriging) to enable a fast prediction of the properties for an extended range of parameters variation and further analysis. The experimental results showed that the High porous alumina ceramics is having an open porosity of 72.3%, and a bulk density 1.2 gm/cm3 and these could be fabricated using PMMA microspheres. Kriging model results showed an acceptable prediction of the experimental-derived data with a maximum discrepancy of 0.02% for the apparent porosity.
