Iron (III) sulfide particles produced by a polyol method

摘要

Iron(III) sulfide Fe_2S_3 particles were produced using a polyol method. Although pyrrhotite Fe_(1-x)S appeared together with Fe_2S_3, the relative yield of Fe_2S_3 changed when the concentration of reagents in the oleylamine changed. M?ssbauer spectra of the particles showed superparamagnetic doublets due to Fe_2S_3 at 293 K, along with a hyperfine magnetic splitting of H = 24.7 T at 6 K. XRD patterns of the Fe_2S_3 suggested a structure similar to that of greigite Fe_3S_4.
