Abstract
A method and a device are provided for removing surface oxides on nodules of a metal powder, before the nodules of the metal powder are used in an industrial process in which the nodules of the metal powder are assembled via a solid route or via a liquid route. In the method and the device, the surface oxides are stripped from the nodules of the metal powder by bringing the nodules of the metal powder into contact with vapour from at least one of: sublimation of a stripping solid material, and sublimation of the stripping solid material followed by a chemical transformation of a product of the sublimation.
