摘要：

The effects of powder washing on the colloidal stability and electrophoretic deposition rate of 3-mol%-Y2O3-doped tetragonal-ZrO2 powder from ethanol suspensions are shown experimentally. Simultaneous acoustic and electroacoustic measurements make it possible to determine independently particle size and zeta-potential in concentrated ethanol suspension, It is suggested that ionic (Na+) surface contamination, which is reduced by laundering cycles, is the cause of the low zeta-potential and deposition rate of the as-received powder.
