Fig. 8From: Mössbauer and Raman characterization of iron-loaded woody charcoal: effects of Fe3+-dispersion in wood on reduction of Fe3+ and graphitization in carbonizationMössbauer spectra at 298 K of Fe5-Y-1 charcoal samples: a Fe5-600-1, b Fe5-650-1, c Fe5-700-1, d Fe3-850-1. Orange solid curve (doublet): high-spin Fe3+ species, blue solid curve (sextet 1): Fe3C, green solid curve (sextet 2): α-Fe, magenta solid curve (singlet): γ-FeBack to article page
