Abstract

The OH− and OD− vibrational frequencies in stoichiometric and nonstoichiometric MgAl2O4 were measured. The nonstoichiometric material had a Al/Mg ratio of 7. The diffusion coefficient of deuterons in the nonstoichiometric material at 1600 K is about 6 ± 3 ⊠ 10−8 cm2/s. Deuterons can readily be swept out by applying an electric field at temperatures above 1000 K.
