Review of the Research Approaches for the Preparation of Ceria-Zirconia Solid Solutions

The research progress of the approaches for the preparation of ceria-zirconia solid solutions is reviewed. Many preparation methods have been applied for the material. These include conventional co-precipitation, sol-gel techniques, the high-energy milling of a mixture of the oxides, a surfactant-assisted approach, a single step solution combustion process, chemical filling and the citrate method et al. Of all these methods, the process of the conventional co-precipitation is simple, and the obtained solid solutions grain size is even, and it is more suitable for mass production.
