Abstract

The paper deals with the properties of a new 4H-SnS2phase (N-phase) synthesized together with berndtite 4H-SnS2by a mechanochemical route from elemental tin and sulphur. The surface and bulk properties of SnS2phases were verified by surface area measurements, particle size analysis, electron microscopy, XRD, Mössbauer spectroscopy and chemical dissolution methods. The particles of synthesized product are 12-18 nm in size and during milling, secondary particles (aggregates) are formed that are 20-60 μm in size. The particle size and a high developed surface area (7-21 m2g-1) greatly influence the solid-liquid reaction and solid transformations of mechanosynthesized tin sulphide products. © 2002 Elsevier Science B.V.
