Phase composition of pyrrhotites 29 years after synthesis

RMS-DPI code:  2010-1-184-0
Scientific session:  F2. Mineralogical crystallography and crystal chemistry.
Author listing:  Onufrienok V.V., Sazonov A.M.

Abstract - Summary 
(short description):
Using the method of dry synthesis in vacuum the iron sulfides with S/Fe ratio from 1.0 up to 1.2 have been obtained. After atmosphere influence in the current 29 years under practically isothermal conditions (~25°Ñ) samples with properties distinct from the original ones have been obtained. The crystal structure and phase structure of iron sulfides as directly after synthesis, so after air storage were investigated using the X-ray analysis method. The samples obtained after air storage contained goethite, pyrite, troilite and pyrrhotite with the phase composition FeS, Fe0.975S, Fe0.950S, Fe0.909S, Fe0.875S. The diagram of the samples phase structure with various S/Fe ratio after long time isothermal air storage has been offered.
Keywords: pyrrhotite, pyrite, goethite, crystal structure, phase composition, synthesis.
