Reactions of chromium with gaseous NaCl in an oxygen environmentTarget collection techniques and high pressure mass spectrometric sampling have been used to study the formation of volatile chromium-containing species in the reaction of Cr2O3 in the condensed state with gaseous O2 and NaCl. Experiments were performed at atmospheric pressure as a function of chromium temperature, oxygen pressure, and NaCl concentration. The major chromium-containing vapor species were found to be (NaCl)xCrO3, with x = 1,2, and 3, which are products of heterogeneous reactions on the surface. The kinetics indicate first order dependence on oxygen and sodium chloride pressures.
