Fe2O3 is insoluble in water and exhibits weak magnetic properties. In contrast, FeO is a black solid with a cubic crystal structure. It has a lower melting point of about 1,377 degrees Celsius and a density of approximately 5.745 grams per cubic centimeter. FeO is soluble in water and possesses stronger magnetic properties compared to Fe2O3.
Iron oxide (Fe2O3) has four crystal structures: γ-, ε-, β-, and α-Fe2O3. Until now, routes of the phase transformations among the four Fe2O3 phases have not been clarified because a systematic synthesis that yields all four Fe2O3 phases has yet to be reported. Herein we report the synthesis of a series of Fe2O3 nanoparticles using …
