| titleOfInvention | Rare-earth modified zirconium-based oxides with nano-core-shell structure |
| abstract | The invention provides a zirconium-based oxide with a nano core-shell structure. The rare earth modified zirconium-based oxide at least includes a core layer and a shell layer, the main body of the core layer is zirconia, and the mass of the zirconia in the core layer is greater than 90% of the mass of the core layer. The core layer and the shell layer can form a nano-spatial framework, which increases the high-temperature stability of the oxide. The main body of the core layer in the rare earth-modified zirconium-based oxide is zirconia, and the weight content of zirconia in the core layer is greater than 90%, so that the atoms in the rare-earth modified zirconium-based oxide form a phase interface in the interface layer, and in it Rearrangement occurs and a dislocation effect occurs, which greatly increases the free energy of the interface, the ceramics after sintering are more compact, and the thermal and electrical properties of the material are well improved. By effectively controlling the addition amount of the rare earth element, the application can reduce the usage amount of the rare earth element, thereby reducing the production cost, and has good economic value. |
