REMOVAL OF OXYGEN FROM SODIUM.

Abstract

Anodic electrolysis of oxide-coated gettering alloys in sodium was evaluated as means of increasing their oxygen removal rate. Twenty-two zirconium and thorium base alloys were tested in sodium thermal convection loops. Detectable increases in gettering rate were observed for unalloyed zirconium and a few other alloys which formed adherent, dense, black films. The gains were not large enough to warrant practical application, apparently due to electronic short circuiting through small film defects. Some of the alloys which formed nonadherent, porous white films achieved higher removal rates than had been hoped for from electrolysis. Zr-13 a/o Ti was the best of these. This alloy produced an oxygen content of less than 1 ppm in sodium and maintained significantly higher removal rates than pure zirconium at all temperatures and oxygen levels. (Author)
