REACTION PATHWAYS IN THE FE-S SYSTEM BELOW 100°C

Benning L.G.; Wilkin R.T.; Barnes H.L. (2000)

The formation pathways of pyrite are controversial. Time resolved experiments show that in reduced sulphur solutions at low temperature, the iron monosulphide mackinawite is stable for up to 4 months. Below 100°C, the rate ...
SURFACE CHEMISTRY AND MORPHOLOGY OF POORLY CRYSTALLINE IRON SULFIDES PRECIPITATED IN MEDIA CONTAINING SULFATE-REDUCING BACTERIA

Herbert R.B.; Benner S.G.; Pratt A.R.; Blowes D.W. (1998)

This study characterizes the surface chemistry and morphology of poorly crystalline iron sulfides precipitated in a chemically defined growth media for sulfate-reducing bacteria. The precipitates were analyzed by X-ray ...
THE COMPOSITION OF NANOPARTICULATE MACKINAWITE, TETRAGONAL IRON(II) MONOSULFIDE

Rickard D.; Griffith A.; Oldroyd A.; Butler I.B.; Lopez-Capel E.; Manning D.A.C.; Apperley D.C. (2006)

The primary FeS precipitate formed from the reaction between Fe(II) and S(-II) in aqueous solutions at ambient temperatures and pressures is nanoparticulate stoichiometric mackinawite, Fe1.00 ± 0.01S. The material is not ...
THE DRY OXIDATION OF TETRAGONAL FES1->X5> MACKINAWITE

Boursiquot S.; Mullet M.; Abdelmoula M.; Genin J.M.; Ehrhardt J.J. (2001)

The gradual oxidation of dry mackinawite (tetragonal FeS1->x5>) has been studied using X-ray diffraction (XRD), transmission electron microscopy (TEM), transmission Mossbauer spectroscopy (TMS) and X-ray photoelectron ...
