A method for producing a metal article may include: Producing a supply of a composite metal powder by: providing a supply of molybdenum metal powder; providing a supply of a sodium compound; combining the molybdenum metal powder and the sodium compound with a liquid to form a slurry; feeding the slurry into a stream of hot gas; and recovering the composite metal powder; and consolidating the composite metal powder to form the metal article, the metal article comprising a sodium/molybdenum metal matrix. Also disclosed is a metal article produced accordance with this method.

Sodium/molybdenum composite metal articles and methods for producing metal articles

Method for producing molybdenum metal powder. The invention includes introducing a supply of ammonium molybdate precursor material into a furnace in a first direction and introducing a reducing gas into a cooling zone in a second direction opposite to the first direction. The ammonium molybdate precursor material is heated at an initial temperature in the presence of the reducing gas to produce an intermediate product that is heated at a final temperature in the presence of the reducing gas, thereby creating the molybdenum metal powder comprising particles having a surface area to mass ratio of between about 1 m/g and about 4 m/g, as determined by BET analysis, and a flowability of between about 29 s/50 g and 86 s/50 g as determined by a Hall Flowmeter. The molybdenum metal powder is moved through the cooling zone.
