Abstract: A method includes introducing metallic powder into a fluidizing chamber of a fluidized bed reactor. A fluidization gas is flowed into the fluidizing chamber. The metallic power becomes entrained in the flow of the fluidization gas. Adsorbed water is removed from the metallic powder by exposing the metallic powder to the fluidization gas for a duration of time and at a treatment temperature to cause the adsorbed water to be removed from the metallic powder.
