Abstract

Molybdenum metal powder. Molybdenum metal powder includes molybdenum metal particles having a surface-area-to-mass ratio of between about 1 m 2 /g and about 4 m 2 /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.

Claims (6)

1. A molybdenum metal powder, comprising:

molybdenum metal particles having a surface-area-to-mass ratio of between about 1 m 2 /g and about 4 m 2 /g, as determined by BET analysis; and

wherein at least about 90% of the molybdenum metal powder particles have a particle size larger than a size 325 standard Tyler mesh sieve.

2. The molybdenum metal powder of claim 1 , wherein the surface-area-to-mass ratio is between about 1.3 m 2 /g and about 3.6 m 2 /g.

3. The molybdenum metal powder of claim 1 , wherein the molybdenum metal powder begins to sinter at about 950° C.

4. The molybdenum metal powder of claim 1 , wherein the molybdenum metal particles have a flowability of between about 29 s/50g and 86 s/50 g as determined by a Hall Flowmeter.
