ceriazirkonia

Ceriazirconia is a solid solution of cerium oxide (CeO2) and zirconium oxide (ZrO2). This ceramic material is known for its exceptional properties, making it valuable in various industrial applications. The combination of ceria and zirconia creates a material with enhanced thermal stability, mechanical strength, and ionic conductivity compared to its individual components.

The exact properties of ceriazirconia can be tuned by altering the ratio of cerium to zirconium, as well as through doping with other elements. For instance, the oxygen storage capacity of ceriazirconia is a key feature, allowing it to readily release and absorb oxygen. This characteristic is crucial in its use as a catalyst support, particularly in automotive catalytic converters where it aids in reducing harmful emissions.

Ceriazirconia also exhibits high ionic conductivity, especially at elevated temperatures. This property makes it a promising material for solid oxide fuel cells (SOFCs) as an electrolyte, facilitating the transport of oxygen ions. Furthermore, its wear resistance and hardness contribute to its application in abrasives and high-performance ceramic components. The synthesis methods for ceriazirconia, such as co-precipitation and sol-gel processes, are important for controlling its microstructure and achieving desired performance characteristics.
