Title:
METHOD FOR PRODUCING MOLYBDENUM GRANULATED POWDER AND MOLYBDENUM GRANULATED POWDER
Document Type and Number:
WIPO Patent Application WO/2012/169257
Kind Code:
A1
Abstract:
This method for producing a molybdenum granulated powder is characterized by comprising: a step in which water is injected into a container, and heated to 50 to 80°C; a step in which a binder is added to the heated water; a step in which an aqueous solution containing molybdenum is prepared by loading molybdenum powder with an average particle size of 1 to 10 μm, to which a tin component and/or a cobalt component has been added, while stirring the water; and a step in which the aqueous 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 a molybdenum granulated powder. The abovementioned method enables a molybdenum granulated powder having the intended average particle size, and containing a tin component and/or a cobalt component, to be efficiently produced at a high yield.
