Abstract
The correlation factor, f, the vacancy availability factor, V, and the jump frequency factor, W, for diffusion of sodium ions in β″-alumina have been calculated as functions of composition and temperature through the application of a Monte Carlo method to a model of nearest neighbour interactions. The results for V and W are in good agreement with those obtained from the pair approximation to the path probability method of Sato and Kikuchi (1971), but results for f are in substantial disagreement because the calculations of these authors do not include the mathematics of the ordered region.Keywords
