Neutron diffraction determination of the structures of deuterium β-alumina at 4.5 and 823 k

Abstract

Refinements of powder neutron diffraction data show that deuterium β-alumina, D₂O·11Al₂O₃, has deuterium atoms bonded to the spacer oxygen at 4·5 K, but at 823 K the deuterium distribution in the mirror plane resembles that found for Na and K β-aluminas providing strong evidence for high deuterium conductivity.
