Molybdenum metal powder and production thereof |
摘要 |
Molybdenum metal powder has surface-area-to-mass-ratios in a range of between about 1.0 meters2/gram (m2/g) and about 3.0 m2/g, as determined by BET analysis, in combination with a particle size wherein at least 30% of the particles are larger than a size +100 standard Tyler mesh sieve. A method for producing molybdenum metal powder includes providing a supply of ammonium molybdate and a reducing gas; causing an exothermic reaction between the ammonium molybdate and the reducing gas at a first temperature to produce an intermediate reaction product and a supplemental reducing gas; causing an endothermic reaction between the intermediate reaction product and the reducing gas at a final temperature to produce the molybdenum metal powder.
