ResumoPowder mixtures of metallic iron and sulfur have been milled in a high-energy planetary ball mill and the formation of iron sulfides has been studied by x-ray diffraction, Mössbauer spectroscopy, and scanning electron microscopy. For Fe:S ratios of 1:1 and 1:2 the final products are FeS with the modified NiAs structure and FeS2(pyrite), respectively. No other iron sulfides were formed for any of the Fe:S ratios studied. The FeS phase has been tested as an electrode material in lithium batteries.
