Correlation among Oxygen Vacancies Protonic Defects and
The distribution of protons and oxygen vacancies at room temperature at different proton concentrations in 10 mol Sc-doped BaZrO3 was investigated to clarify the influence of proton concentration and oxygen vacancies in the trapping of protons caused by the acceptor dopant. To enhance proton conductivity for practical use it is essential to understand this phenomenon known to limit the long

CaZrO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ca2 is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.34–2.89 Å. Zr4 is bonded to six O2- atoms to form corner-sharing ZrO6 octahedra.

Neutron Scattering Studies of Compositional Heterogeneity
Rietveld analyses of neutron diffraction data collected on a series of Pb(Zr0.5Ti0.5)O3 samples which had been prepared by sol−gel and conventional mixed oxide methods showed that each sample contained both rhombohedral and tetragonal PZT (Pb Zr1-xTix O3). The zirconium-to-titanium ratio in the two phases was found to be markedly different.
