Abstract

In this study, the formation of magnetite using Fe(II) and Fe(III) hydroxides was investigated; The effects of hydroxide synthesizing pH and temperature, reaction temperature, and total water volume of hydroxide suspensions on the magnetite formation were studied. And the basic reaction behaviors of magnetite formation was discussed in the view of hydroxide formation reaction of Fe(II) and Fe(III) by titration. The characteristics of products were examined by TEM, VSM, XRD. From these experimental data, solid-solid reaction between Fe(II) and Fe(III) hydroxides is proposed as a new ferrite formation mechanism.
