The preparation of dense homogeneous zirconiatoughened alumina ZTA with high drysliding wear resistance is described. These ZTA ceramics are obtained by sintering green compacts, made by colloidal filtration of welldefined ZrO 2 Al 2 O 3 particle suspensions, for 2 h at 1400C. The optimum solid and stabilizer concentrations for the filtration process were determined.
