Webbcorresponding to b-FeOOH in the presence of silicate ions is weaker than that in their absence. Thus, the conversion of Fe(OH) 3 to b-FeOOH and/or the growth of -FeOOH parti-cles in aging for 30d seems to be suppressed by the addi-tion of silicate ions. Further aging for 90d leads the conver-sion from b-FeOOH to a-Fe 2 O 3 particles ...

Similar to pyrite-type FeO 2 H x (0 < x < 1), ε -FeOOH x may exist as a solid solution of ε -FeOOH and FeO 2 [ 8 ]. 2. Webb1 juli 2024 · Out of the seven Raman active phonon modes predicted by group theory (2A 1g + 5E g) in the corundum-type (α-Al 2 O 3), structure of the hematite (D 3 d 6 space group), six modes were detected (2A 1g + 4E g), dash line in Fig. 1.
