چکیده
The crystallochemical characterization of magnetic spinels prepared from aqueous solution has been studied primarily by electron microscopy and 5 Fe Mossbauer spectroscopy. . Two synthetic routes investigated : 7Fe have been t : method 1; partial oxidation of Fell solutions " in the presence of NO;; at 100°C, O C , and method 2; reaction of hydrated Fe oxide (ferrihydrite) with Fell ions at room temperature, pH = 7, 8 and 9. Both routes gave small (10-60 0 (Fe,O,) 0 4) particles that were readily oxidised to rrr "
