Fig. 7From: Mössbauer and Raman characterization of iron-loaded woody charcoal: effects of Fe3+-dispersion in wood on reduction of Fe3+ and graphitization in carbonizationHT-dependence of iron species yield in Fe3-700-Z and Fe3-850-Z charcoal samples. Open mark: Fe3-700-Z charcoal, full mark: Fe3-850-Z charcoal. Orange circle: high-spin Fe3+, blue rhombus: Fe3C, green square: α-Fe, magenta triangle: γ-FeBack to article page
