Abstract

Amorphous nanomaterials in the ZrO2-CeO2 system are synthesized. The aging and crystallization processes in a complex zirconium-cerium hydrogel are investigated. Powders with a crystal size of 45–100 nm are prepared. Samples having a porosity of less than 2.2% are produced from the powders. It is demonstrated that tetragonal zirconia-based solid solutions Zr1−x CexO2−δ sintered at a temperature of 1500°C possess ionic conductivity in air and in noble gasses. The assumptions are made regarding the mechanisms of ionic (surface anionic) and electronic (hopping) conduction in samples of the 88ZrO2 · 12CeO2 (mol %) composition. The solid solutions prepared can be used at a temperature of 720°C as high-strength inexpensive solid electrolytes.
