Surface oxidation in glassy arsenic trisulphide induced by high-energy [gamma]-irradiation

Influence of high-energy [gamma]-irradiation with ~3 MGy dose on glassy g-As sub(2)S sub(3) was investigated by a complex of scanning electron microscopy, energy-dispersive X-ray spectroscopy and X-ray diffraction methods. A white layer composed of separate 1-2 [mu]m rhombohedral arsenolite As sub(2...

Description
Summary:Influence of high-energy [gamma]-irradiation with ~3 MGy dose on glassy g-As sub(2)S sub(3) was investigated by a complex of scanning electron microscopy, energy-dispersive X-ray spectroscopy and X-ray diffraction methods. A white layer composed of separate 1-2 [mu]m rhombohedral arsenolite As sub(2)O sub(3) crystallites was observed at the surface of [gamma]-irradiated samples. These As sub(2)O sub(3) extractions along with crystallised S allotropes are responsible for expansion of the first sharp diffraction peaks in the XRD patterns of g-As sub(2)S sub(3).
