Chemical and Structural Changes in Manganese‐Doped Yttria‐Stabilized Zirconia Studied by Electron Energy Loss Spectroscopy Combined with Electron Diffraction

Solid solution of manganese in yttria‐stabilized zirconia (YSZ) may occur in the electrolyte of solid oxide fuel cells. Possible changes in valence, coordination, and site occupancy of Mn in YSZ are of interest. Also, subsequent structural modification of the cubic YSZ, as well as the possible ordering of vacancies, has important consequences for the ionic conductivity. Electron energy loss spectroscopy was used to measure the O K and the Mn L …
