Inorganic Materials Aims and scope

Abstract

Data are presented on the phase composition of ZrO2–Al2O3–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 Al2O3 content of 30 mol %, the M-ZrO2 content is independent of the precipitation procedure.
