Melt refining of synthetic EBR-II alloy in stabilized zirconia crucibles at 1400°C for three hours under one atmosphere of helium pressure resulted in almost complete volatilization of iodine from ingot and skull fractions. Removal of iodine was strongly dependent on refining temperature. Volatilized products were primarily iodides of metals initially present as minor oxide constituents of the crucible; no evidence for evaporation as free iodine was found in the melt refining operation.
