Abstract

The solubility of oxygen in liquid lead bismuth eutectic (LBE) was determined by using electrochemical methods. The oxygen partial pressure in oxygen saturated LBE was measured from 475 to 724 K by using an oxygen sensor comprised of yttria partially stabilized zirconia and air/LSM (Lanthanum strontium manganite) reference electrode. Sieverts’ constant of the dissolved oxygen in LBE was measured from 598 to 748 K by coulometric titration method using the oxygen sensor. The measured oxygen partial pressure in oxygen saturated LBE (PO2(LBE−PbO) in bar) and Sieverts’ constant of dissolved oxygen in LBE (k for 1 wt.% standard state) are given by log PO2(LBE−PbO) = 11.52 − 22996/T (475-724 K), log k = 3.12 − 7072/T (598-748 K) respectively. Combining the measured data, the oxygen solubility in LBE (CO,S in wt.%) was derived and it is given by logCO,S = 2.64 − 4426/T (598-724 K).
