Abstract

An examination was conducted on the effects of a temperature gradient on the distribution of iron and aluminum cations in iron aluminate spinels for the cases where the cation vacancies have been completely restricted or allowed to flow freely. A comparison of both cases yields insight into the mechanisms through which segregational forces act and their relative magnitudes of importance. This paper examines the conditions under which cation segregation can be expected in oxide solid solutions where the oxygen sublattice is essentially rigid relative to the mobile cations.
