Abstract: A porous iron powder consisting essentially of a reduced iron powder having a specific surface area above 3000 m2/kg. The reduced iron powder is ferric oxide in a hydrogen environment and mechanical fluid bed operating at barometric pressure. The hydrogen environment has a pH2/pH2O ratio above 2.3. The reduced iron powder is ferric oxide produced by roasting of a solution of ferrous chloride. The end-product particle size is between 1 and 45 microns and has an in-vitro dissolution rate of 100% in at most twenty minutes.

Abstract: A process of producing metal powders by feeding a metal oxide and a reducing agent into a rotary reactor to form a mechanical fluid bed. The fluid bed is rotated with a rotation speed of about 100 rpm. The fluid bed is then heated to a reaction temperature of up to 1200° C. The pressure is then set within the rotary reactor to a pressure in a range of 0.001 bars to 2.0 bars, as a result reducing the reaction temperature to a temperature in a range of 600° C. to 1200° C. Finally, the pressure and the rotation are maintained, wherein a high value metal powder is formed without the requirement for post-grinding process steps. A product resulting from specific settings of the process include a high value molybdenum powder capable of being used as a chemical catalyst and other specialty applications specific to the metal, eliminating costly production methods.

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.
