Generation of charge carriers during combustion synthesis of sulfides
Recent experimental studies on generation of electric voltage during combustion synthesis of zinc sulfide (ZnS) have revealed high-voltage signals (4 V) with a duration of around 1 s, which is at least four times higher than those produced by the gas-solid and solid-solid combustion reactions studied previously. These data have raised the question about mechanism of the phenomenon. In this work, we developed a novel (distributed) model describing the generation electric potential during combustion synthesis of sulfides (CSS). Simulations of the evolution in the behavior of charge carriers and voltage profiles suggest that it is the emission of negatively charged sulfur ions as well as electrons that has a strong impact on the amplitude and temporal evolution of combustion-induced voltage.
