Present paper shows the alumina based catalyst supports synthesis process investigation, with improved properties than existing. Process was optimized to determine suiting polymer foam porosity, suspension contents, clay addition and sintering temperature. Polymer foams of 10 and 20 PPI (pores per inch) were soaked into suspension that consisted of α-alumina with 30 mas.% of clay (‘VN-25’), with lower sintering temperature for the process economic enhancement. Sintering temperature was optimized for suitable mechanical properties. Green bodies were sintered at five temperatures, from 1573 to 1773 K for 60 minutes. The best mechanical properties were obtained with VN-25 suspension, 10 PPI polyester foam, sintered at 1673 K for 60 minutes. The compressive strength of this system, achieved in the above temperature-time mode, was 6.2 MPa.
