In a non-isothermal flowing sodium/stainless steel system iron, chromium, and nickel are dissolved from the high-temperature regions and deposited in the lower temperature regions because of supersaturation. Included in this process of mass transfer is the formation and decomposition of various transition metal and sodium double oxides. In addition, the formation of a double-oxide would also lower the oxygen activity in the sodiun system if the double oxide is thermodynamically more stable than Na2O. The main objective of the present study is to assess the effect of double oxides, particularly sodium chromite (NaCrO2), on the oxygen activity in a typical sodium/stainless steel system.
