Reaction of a Mixture of Bismuth and Iron Oxides with Chlorine and Sulfur Dioxide

摘要

The processes in a heterogenous multicomponent system Bi2O3-Fe2O3-Cl2-SO2.are explored.In the temperature range 300-700°C is clearly developed mutual influence of chemical reactions at introducing to the system of an additional component:chloridosublimation of both bismuth and iron in the presence of SO2 and chloridosublimation of bismuth at adding iron oxide to bismuth oxide are accelerated.In the region of the higher temperatures the possible chemical reactions in the system proceed independently:SO2 only dilutes chlorine and mutual influence of bismuth and iron oxides is not found.
