Diffusion Path Networks in Oxides
An understanding of diffusion mechanisms in oxides, particularly cation diffusion, must take account of the various possible paths which an atom may follow in going from one normally occupied site to another equivalent site. Such paths may be branched and will likely include stops at metastable points along the way. This chapter describes methods whereby path networks within oxides can be characterized, and discusses diffusion in the structures NaCl, ZnS, FeS, and BeO.
