Description: | The results of complex study of the processes of dehydration, crystallization and phase transitions in systems based on zirconium dioxide under the influence of temperature, high hydrostatic pressure and doping (Gd or Y). Discovered change the energy state of the surface at certain temperatures and pressure that affects the behavior of nanoparticles in system and and allows you to manage their functional properties. Stability of nanoparticles to the tetragonal-monoclinic transition depends not only on the amount of dopant and particle size, but also as their surface, which can be changed by reconstruction or relaxation due to desorption of OH groups, residual chlorine, vacancy formation and their replacement with oxygen when heated powder during synthesis. Processing pressure can lead to a consolidation and deahrehatsiyi nanoparticles. |
