| Iron oxides | |
| Iron oxide powders were obtained by the isothermal decomposition of ferric citrate in an oxygen atmosphere at different temperatures. Throughout the experiments, the product of decomposition was a mixture of maghemite (ϒ-Fe2O3) and hematite (α-Fe2O3. with different relative proportions and particle size distributions. After TGA and DTA measurements, a decomposition temperature of 300°C was chosen, and a maximum specific saturation magnetization of about 40 emurg was obtained. Most of the product particles were less than 1 μm in size, including a superparamagnetic fraction, as evidenced by Mössbauer spectroscopy. | |
