Mixed oxides of cerium and zirconium as well as solid solutions and cerium oxides are produced having improved thermal stability. The process involves the formation of cerium and zirconium oxides, mixed oxides and solid solutions by methods such as co-thermohydrolysis and co-precipitation, followed by washing or impregnating with an alkoxylated compound having greater than 2 carbon atoms. After the washing or impregnating step, the mixture is calcined to form oxides having very high surface area and oxygen storage capacity. The improved thermal stability of the oxides makes them advantageous for use in applications such as catalytic converters.
