N2 - Corn starch was used as a templating agent, and an oxide mixture containing alumina, magnesia, zirconia and yttria was added in the sol-gel state. After slip casting, curing at 85 °C, drying and sintering, high-performance porous alumina ceramics were obtained. The properties of the porous alumina ceramics were analyzed by means of SEM, XRD, flexural strength and porosity. The research findings showed that, when the starch content was 1 wt%, the prepared ceramic mainly consisted of four phases: α-Al2O3, MgAl2O4, ZrO, and YSZ. The flexural strength reached 157.27 MPa, the flexural strength of the green body was about 3 MPa, and the porosity was around 30%.
