Densification behavior of powder compacts having a cordierite composition prepared by the sol-gel process using metal alkoxides is studied. The calcination of the alkoxy-derived powder at 800°C for 12h gave the best sintering. Densification of the powder compacts occurred from 800° to 900°C. Dense cordierite ceramics with different crystalline phases or properties were obtained by sintering the powder compacts without any sintering aid. The sintering of the powder compact at 1300°C for 12h gave dense α-cordierite ceramics having the flexural strength of 120MPa and the critical stress intensity factor of 2.8MN/m^3/2.
