Oxygen ion mobility in the cubic fluorite‐structure phase having the composition Zr 0.85 Ca 0.15 O 1.85 has been directly determined by exchange measurements employing the stable isotope O 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.
