microstructural characterization of yttria stabilized
Crystallographic Characteristics of Grain Boundaries
Grain-boundary plane misorientation angle grain size and grain-boundary energy distributions were quantified using electron backscatter diffraction data for dense polycrystalline yttria-stabilized zirconia to understand interfacial crystallography in solid oxide fuel cells. Tape-cast samples were sintered at 1450°C for 4 h and annealed for at least 100 h between 800°C and 1650°C.

In this work ceramic foams of 3 and 8 mol yttria-stabilized zirconia (3YSZ and 8YSZ) were manufactured by the replication method using polystyrene-polyurethane foams with pore sizes in the 7–10 ppi range. A second coating was carried out on presintered foams in order to thicken struts and hinder microstructural defects.

The structural properties of polycrystalline yttria-stabilized zirconia (YSZ) have been studied using FT-Raman spectroscopy X-ray diffraction and X-ray photoelectron spectroscopy (XPS). Yttria content was varied between 8 and 15 (by mole fraction) to determine compositional effects on YSZ phonon structure lattice parameter and oxidation state.

Trace impurities in coal-derived syngas pose a threat on the performance and durability of solid oxide fuel cells (SOFCs) operated in syngas. A Ni-YSZ/YSZ/Ni-YSZ (YSZ stands for yttria-stabilized zirconia) half-cell is constructed in order to evaluate the effects of a phosphorus impurity on the performance of the Ni-YSZ cermet anode in the simulated coal-derived syngas containing 30.6 H 2 30
