Formation of iron oxide powder in a hot-wall flow reactor: Effect of process conditions on powder characteristics

Nanometer-sized iron oxide powder was prepared by reaction of iron pentacarbonyl (Fe(CO)5) and oxygen in a gas phase reactor. X-ray diffraction and differential thermal analysis revealed that depending on the reaction temperature α-Fe2O3 (temperature>600°C) or the thermodynamically less stable γ-...
