Web1 de out. de 2024 · FeS2 has two common crystal structures, cubic-system pyrite and orthorhombic -system marcasite. Fig. 1 (a) and (b) show the schematic view of pyrite and marcasite structured FeS 2. The lattice parameters of pyrite are a = b = c = 0.54 nm, the bond length of Fe-S and S-S are 0.23 nm and 0.21 nm, respectively. Web9 de jun. de 2024 · The conditions for Fe 3 S 4 formation are shown to be dependent on both the temperature (∼60 °C) and the availability of sulfur to drive a FeS to Fe 3 S 4 transformation. Upon further cycling, Fe 3 S 4 transforms to a lower sulfur content iron sulfide phase, a process which coincides with the loss of sulfur based on the new …
