Effect of preparation conditions on the phase composition of ZrO 2-Al2O3-CeO2 powders

Article abstract of DOI:10.1023/A:1021319320332

Data are presented on the phase composition of ZrO₂-Al ₂O₃-CeO₂ powders containing 10, 30, and 70 mol %, prepared via coprecipitation and successive precipitation. The precipitation procedure is shown to have a strong effect on the phase composition of the heat-treated powders and the state (inter- or intracrystalline) of the T-ZrO₂ phase, thereby changing its stability. At an Al ₂O₃ content of 30 mol %, the M-ZrO₂ content is independent of the precipitation procedure.
