A comparison of the dissolution behavior of troilite with other …
网页2003年3月1日 · Diffraction peaks other than those accounted for by troilite were present in the XRD pattern (Fig. 1) indicating the presence of other phases. Clinochlore (Mg, Fe, Al) 6 (Si, Cr) 4 O 10 (OH) 8, a complex metal silicate hydroxide, was identified as a minor phase. A third, unknown phase was also detected as reflections in the low 2θ range.
Nanocrystalline Iron Monosulfides Near Stoichiometry
网页2018年4月26日 · For stoichiometric FeS, the two crystal phases that have received the most attention are troilite and mackinawite. Troilite is predicted to exhibit large room temperature magnetoelectricity,...
网页The XRD pattern from the Toluca troilite is dominated by reflections from troilite, with weak reflections for graphite and daubréelite (FeCr2S4), and minor schreibersite ((Fe,Ni)3P) and cohenite ((Fe,Ni,Co)3C. Reflectance spectra of the metal and troilite mixtures are shown in …
