Abstract
The structure of the high-temperature solid solution Li1.6Ag0.4SO4 has been determined from neutron and X-ray powder diffraction data. The sulphate groups form a fcc lattice where the lithium ions are found to occupy the ±(1/4, 1/4, 1/4) tetrahedral sites. The silver ions partly occupy the same sites and partly the larger (½, ½, ½) octahedral site. The results strongly support earlier conclusions for the fcc phase of Li2SO4. Exceptionally high temperature factors are found. The consistency of the structural model with other characteristic properties of the high-temperature fcc phase is briefly discussed.
