A similar mechanism envisages that oxygen ions diffuse across the film from the outer surface towards the metal (Figure 8.24b). The oxygen ions cannot be generated spontaneously and, once again, it is necessary for electrons to move through the... [Pg.246]

Consider an MO oxide where ions move by the vacancy mechanism and the activation energy of metal ion diffusion, Qm, is higher than that of oxygen ion diffusion, go, Qm> Qo)-... [Pg.194]

In theory, heat in crystalline solids is transferred by three mechanisms (i) electrons (ii) lattice vibrations and (iii) radiation [44], Since zirconia is an electronic insulator (electrical conductivity occurring at high temperatures by oxygen ion diffusion), electrons play no part in the total thermal conductivity of the system. Hence, thermal conduction in zirconia-based ceramics is mainly by lattice vibrations (phonons) or by radiation (photons). [Pg.9]
