Investigation of Plasma Sprayed and Constrained-Sintered Zirconia Based Electrolytes

This study investigates the effects of sintering on conventional and nanostructured plasma sprayed YSZ. In order to gain a better understanding of the differences in sintering behavior, the layers are sintered under constrained and non-constrained conditions over a temperature range of 800 to 1520 °C. The influence of particle size on sintering kinetics, microstructure development, electrical properties, and thickness is assessed for free-standing layers as well as deposits on rigid substrates.
