Description
Summary:Oxygen ion mobility in the cubic fluorite-structure phase having the composition Zr sub 0.85 Ca sub 0.15 O sub 1.85 has been directly determined by exchange measurements employing the stable isotope O exp 18 and mass spectrometer analysis. Measurements of electrical conductivity have been carried out as a function of both temperature and oxygen pressure. Results indicate that the conductivity is wholly ionic with a transfer number near unity for the oxygen ion.
