Abstract
We have studied phase formation processes during heat treatment of precipitates in the ZrO2-Al2O3 and ZrO2-CeO2-Al2O3 systems. During heat treatment of powders prepared by coprecipitation of precursors to ZrO2, CeO2, and Al2O3, α-Al2O3 is formed at higher temperatures, which is due to the formation and decomposition of T-ZrO2 and metastable Al2O3 phases. The precipitation sequence in the ZrO2-CeO2-Al2O3 system influences the lattice parameters of the forming T-ZrO2-based solid solutions because of the different degrees of Ce4+ and Al3+ substitutions for Zr4+.
