Abstract: High-purity iron powder products produced by a low-temperature process by feeding hematite and a reducing agent into a rotary reactor under pressure to form a mechanical fluid bed. The fluid bed is rotated at a particular speed within a rotary reactor. The fluid bed is simultaneously heated to a reaction temperature, and the pressure is then reduced within the rotary reactor to a pressure in a range of 0.01 bars to 2.0 bars, as a result reducing the reaction temperature to a temperature in a range of 600° C. to 850° C. Maintaining the pressure and the rotation results in the formation of a high-purity iron oxide without the requirement for post-grinding process steps because sintering is prevented by using a combination of pressure reduction and a rotary set at an optimum rotation speed, resulting in useful additives produced by a more environmentally-friendly process.
