Synthesis of tin (II) sulfide: Determination of the reaction kinetics through calorimetric techniques

In the last ten years, the search for new materials for new applications has become one of the 'must' in the field of powder technology. Particularly, as regards solid lubricants, concerns in the use of compounds containing lead and antimony have been raised, since the former is classified as a carcinogen and the second as a suspect one. Therefore, as a consequence of both more stringent law requirements for environmental emissions and low impact on human health, safe and cheap materials are strongly desired. Tin (II) sulfide (SnS) has emerged as a promising alternative due to its favorable properties. This study aims to determine the reaction kinetics of the synthesis of SnS through calorimetric techniques. We employed an experimental approach to analyze the thermal behavior of the reaction between tin and sulfur under various conditions. The results indicate that the reaction is highly exothermic and that the kinetics are influenced by the stoichiometric ratios of the reactants. Our findings contribute to a better understanding of the synthesis process of SnS, providing insights for optimizing its application in various fields. This research highlights the potential of SnS as a viable material for future applications in powder technology.
