Abstract

In this paper, Nanoslurry-ZrO2 were added into alumina powders to improve the bending strength of macroporous AI2O3 Ceramic sintered at 1550°C, 1600°C, 1650°C corresponding for3h each in air, respectively. The results show that the bending strength of porous alumina ceramic was simultaneously greatly influenced by various ZrO2 contents. When ZrO2 content is 2wt%, the maximum bending strength value of sample heated at 1650°C was observed, which achieves to 50 MPa. And the maximum bending strength value of any sample also exists at 1650°C By SEM analysis, many fine ZrO2 particles with high activity surface form a neck bonding which is beneficial to the improvements of bending strength.
