METHOD FOR PRODUCING MOLYBDENUM GRANULATED POWDER AND MOLYBDENUM GRANULATED POWDER |
摘要 |
<p>This method for producing a molybdenum granulated powder is characterized by comprising: a step in which an organic solvent is placed in a container; a step in which polyvinyl butyral is added to the organic solvent as a binder; a step in which a solution containing molybdenum is prepared by loading molybdenum powder with an average particle size of 1 to 10 µm, to which at least one of a potassium component, an aluminum component and a silicon component has been added, while stirring the organic solvent; and a step in which the solution containing molybdenum is loaded in a spray dryer in which, when the rotation speed of a rotator of the spray dryer in which the solution containing molybdenum is to be dispersed is regarded as A (rpm), and the average particle size of the granulated powder is regarded as B (µm), A/B ranges from 50 to 700, and the solution containing molybdenum is dispersed and dried to prepare the molybdenum granulated powder. The abovementioned method enables a molybdenum granulated powder having the intended average particle size to be efficiently produced at a high yield.</p> |
