Chemistry of Carbonate-Sulfur Flux
Q. Won Choi, Han Choi, So-Young Chang, Chong-Hong Pyun, Chang-Hong Kim*
Reactions of alkaline metal carbonates with sulfur are investigated in detail. The evolution of CO and a trace of SO2 were observed in the course of reaction with major component of polysulfides. Some evidences that the reaction proceeds with breaking of terminal sulfur-sulfur bond in the sulfur polymer, and forming CO, SO2 and polysulfide are presented. Polysulfides have the role of keeping free sulfur and allow it to react with other chemicals to rather high temperatures.
