Abstract: A gas atomization apparatus is disclosed for producing high purity fine refractory compound powders. After the system reaches high vacuum, a first stage inert atomizing gas breaks superheated metal melt into droplets and a second stage reactive atomizing gas breaks the droplets further into ultrafine droplets while reacts with them to form refractory compound powders. The first stage atomizing gas is inert gas able to break up melt into droplets and prevent crust formation on the nozzle front. A reaction time enhancer is arranged at bottom of reaction chamber to furnish a reactive gas flow in a reverse direction of the falling droplets and powders. Under the reverse gas flow, the falling droplets and powders change moving direction and travel longer distance in reaction chamber to increase reaction time. This apparatus can produce refractory powders with ultrahigh purity and uniform powder size while maintain high process energy efficiency.

Abstract: Refractory metal powders are dehydrided in a device which includes a preheat chamber for retaining the metal powder fully heated in a hot zone to allow diffusion of hydrogen out of the powder. The powder is cooled in a cooling chamber for a residence time sufficiently short to prevent re-absorbtion of the hydrogen by the powder. The powder is consolidated by impact on a substrate at the exit of the cooling chamber to build a deposit in solid dense form on the substrate.
