The Structure of synthetic Fe3S4 and the Nature of Transition to FeS

TLDR: The transition between Fe3S4 and FeS seems to depend closely on their structures as discussed by the authors, and the transition between the two structures seems to be dependent on their respective structures.

Abstract: Synthetic Fe3S4 is cubic, a0 = 990 A, space group Fd3m, Z = 8 The parameter u of sulfur positions in 32e site is estimated as 3/8, i e it has an ideal structure Fe3S4 was decomposed to tetragonal or hexagonal FeS and free S at below or above 190 °C under hydrothermal conditions The transition between Fe3S4 and FeS seems to depend closely on their structures Synthetisches Fe3S4 ist kubisch, a0 = 9,90 A, Raumgruppe Fd3m, Z = 8 Der Parameter u der Schwefelatome in 32e Lage ist 3/8, d h es hat eine ideale Spinellstruktur Unter hydrothermalen Bedingungen wird Fe3S4 in tetragonales oder hexagonales FeS und freien S unter oder uber 190 °C zersetzt Der Ubergang zwischen Fe3S4 und FeS scheint stark von ihren Strukturen abhangig zu sein
