Abstract
Nanocrystalline 10 mol.% yttria-stabilized zirconia (YSZ) electrolyte was synthesized via the plasma spray technique. The ionic conductivity was measured using AC impedance spectroscopy within the temperature range 350–600 °C in air. The measured total ionic conductivity of plasma-sprayed YSZ electrolyte is ∼2.3 times higher than that of sintered YSZ electrolyte at 600 °C in air. The improvement in ionic conductivity is ascribed to the nanocrystalline grain size and siliceous free grain boundary with grain-to-grain contact.
