Abstract
Densified molybdenum metal powder and method for producing same. Densified molybdenum powder has substantially generally spherical particles, surface area to mass ratio of no more than about 0.5 m2/g as determined by BET analysis, and a flowability greater than about 32 s/50g as determined by a Hall Flowmeter. A method for producing densified molybdenum metal powder includes providing a supply of precursor material of molybdenum metal powder particles reduced from ammonium molybdate; providing a supply of reducing gas; densifying the precursor material in the presence of the reducing gas; and producing the densified molybdenum metal powder.
