Synthesis of materials with high thermal stability based on cerium and zirconium oxides

The work is devoted to the investigation of the effect of the post-precipitation treatment of the slurry of cerium, zirconium, yttrium and lanthanum mixed hydroxides on surface parameters and porosity of quaternary solid solutions of the composition Zr0.5Ce0.4Y0.05La0.05Ox. Synthesis conditions in w...

Zusammenfassung:The work is devoted to the investigation of the effect of the post-precipitation treatment of the slurry of cerium, zirconium, yttrium and lanthanum mixed hydroxides on surface parameters and porosity of quaternary solid solutions of the composition Zr0.5Ce0.4Y0.05La0.05Ox. Synthesis conditions in which the stabilization of the precipitate by surfactants led to an increase in the thermally stable specific surface area of the materials were determined.
