Abstract
Molybdenum metal powder, and method for production thereof. Molybdenum metal powder has surface-area-to-mass-ratios in a range of between about 1.0 meters/gram (m/g) and about 3.0 m/g, as determined by BET analysis, in combination with a particle size wherein at least 30% of the particles have a particle size larger than a size +100 standard Tyler mesh sieve. In addition, molybdenum metal powdermay be further distinguished by flowability in a range of between about 29 seconds/50 grams (s/50 g) and about 64 s/50 g, as determined by a Hall Flowmeter. A method of producing molybdenum powder may comprise providing a supply of ammonium molybdate, heating the ammonium molybdate at an initial temperature in the presence of a reducing gas to produce an intermediate product, and heating the intermediate product at a final temperature in the presence of the reducing gas, producing molybdenum metal powder.
