Abstract The molten alkali carbonate eutectic consists of essentially equal parts by weight of lithium, sodium and potassium carbonate. It may be used to control SO2 air pollution by scrubbing stack gases with the molten salt. The resultant fused salt contains sulfite which disproportionates to sulfate and sulfide. Suitable containment of these molten salts in H2O, CO2, and H2S gaseous environments is required for commercial development of this technique to control air pollution. The results of screening, medium-term and long-term static, dynamic, and thermal cycle tests are given. At 500C, SS 347 appears to contain all of the above melts satisfactorily. At higher temperatures, containment of these melts requires high-chromium alloys, ceramics, cermets, or a frozen skull of the salt. Materials for the Small Pilot Plant are recommended and the future corrosion program is outlined. (Author)
