Abstract

This paper presents a NMR study of mixed alkali effects in δ-aluminas. It is shown that the BPP theory of relaxation does not describe the NMR results. However, with an elementary analysis of the data, NMR yields information about the cation dynamics which substantially agrees with the diffusion measurements.
