Defects and Diffusion in Ceramics III

This is the third special issue to cover recent progress in the field. As usual, priority in abstracting has been given to the most accessible work and, in particular, to those papers which furnish original data or report important new techniques, phenomena or anomalies; although there is also extensive coverage of more qualitative features of diffusion and defect phenomena, of the predictions of computer models, and of theoretical studies. As before, the usual definition of ‘ceramic’ has been widened so as to include all forms of carbon, and also some nitrides whose primary use is not that of a classical ceramic.
