摘要:
Oxygen ion mobility in the cubic fluorite‐structure phase having the composition Zr0.85Ca0.15O1.85has been directly determined by exchange measurements employing the stable isotope O18and 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 io
