摘要：

Tin exhibits different oxidation kinetics which are composition dependent, when it forms intermetallic compounds with the chalcogenides S and Se. This phenomenon is related to the layer compounds SnS2 and SnSe2 crystalline structure. These minerals have anisotropic bonding characteristics, due to Van der Waals bonds presence between chalcogenides adjoining planes. The mentioned weak bonds allow the oxygen diffusion to the bulk, favouring the reaction with the inner tin atoms. In this work we study samples of Sn-S alloy with different thermal treatment by XRD and Mossbauer spectroscopy. Results are discussed and compared with those obtained for Sn-Se alloy in an early work [1].
