Sodium Sulfur

Raman EPR and visible absorption spectra of sodium tetrasulfide in the solid state and melts have been studied from room temperature up to 300°C. The above techniques provide strong evidence for breaking of the polysulfide chains resulting in the production of S3-radical ions. The existence of the radical ions in polysulfides at elevated temperatures is important for understanding the electrode processes in sodium sulfur batteries.

The salts Na2S2O6, Na2S2O6•2H2O, K2S2O6, BaS2O6, and BaS2O6•2H2O were irradiated at room temperature with 60Co gamma rays. When the irradiated salts were dissolved in water sulfite ions, sulfate ions, and acid were found as irradiation products. The dependence of yield upon absorbed dose was studied. The G-values found ranged from unity to 20. Thermal annealing of the irradiated salts had only a slight effect on product yields. For BaS2O6 there is a large increase in product yields after a dose of 28.3 × 1022 eV per mol has been absorbed. A mechanism involving SO3− and S2O6− radical ions is proposed.
