Investigation of Some Physicochemical Properties of Ceramics, Single Crystals, and Nanofilms Based on Zirconia, Hafnia, and Rare-Earth Oxides

摘要

Precursor powders in the ZrO2-CeO2-Sc2O3-Al2O3 system have been prepared using the sol-gel method. A physicochemical analysis of the synthesized ceramics, single crystals, and nanofilms based on ZrO2 and HfO2 oxides has been performed. It has been revealed that the introduction of alumina Al2O3 into the ZrO2-based ceramic samples reduces the thermal expansion coefficient and that these ceramic materials possess a high electrical conductivity as compared to the other materials under investigation.
