Chemical stability of beta-alumina

OSTI ID:6833186
Beta-alumina tubes can fracture under conditions which arise during the operation of Na/S cells. Several models, based on sodium ion focusing at the crack tip, have been proposed to explain the failure mode and are discussed in recent papers. In this study, two beta-alumina compositions that are used in developmental cells were immersed in molten sodium to differentiate the chemical effects of electrolyte degradation from the electrochemical ones. Tests were also conducted in sodium polysulfide melts because electrolyte deterioration on the sulfur side has also been reported.
