| Abstract Scope |
High temperature dielectric properties of graphitic-carbon coated 8.0 mole% Y2O3-stabilized ZrO2 (8YSZ) nanoparticles (NPs) were studied in ambient air. The platelet-shaped NPs were synthesized by a simple chemical process. The process permits fine tuning of the morphology of the NPs along with the formation of an in situ grown surface layer of graphitic-carbon. The morphology and surface structure of the 8YSZ NPs were studied by high resolution transmission electron microscope and Raman spectroscopy. The graphitic-carbon layer plays a critical role in controlling the dielectric properties of the platelet-shaped 8YSZ NPs. Here, we report on the high temperature dielectric characteristics of the 8YSZ NPs in correlation with their surface structure. |
