Precipitation of Iron Oxides from Dense p-FeOOH Suspensions

4 PRECIPITATION OF IRON OXIDES FROM DENSE p-FeOOH SUSPENSIONS 

Characteristic XRD patterns of the particies formed during the transformation of p-FeOOH to a-Fe20s in dense suspensions at 160 °C for the starting concentration of (a) 0.1 M AAS and (b) 0.001 M AAS. The corresponding times of precipitation are denoted. AAS ammonium amidosulfonate. (Reproduced from Ref. 86 with permission of Elsevier.)
