METHOD FOR PRODUCING MOLYBDENUM CARBIDE GRANULATED POWDER AND MOLYBDENUM CARBIDE GRANULATED POWDER

Document Type and Number:

WIPO Patent Application WO/2012/169260

Kind Code:

A1

Abstract:

This method for producing a molybdenum carbide 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 carbide is prepared by loading molybdenum carbide powder with an average particle size of 1 to 10 μm while stirring the water; and a step in which the solution containing molybdenum carbide is loaded in a spray dryer in which, when the rotation speed of a rotator of the spray dryer is regarded as A (rpm), and the average particle size of the molybdenum carbide granulated powder is regarded as B (μm), A/B ranges from 50 to 700, and the solution containing molybdenum carbide is dispersed by the rotor, and then dried to prepare molybdenum carbide granulated powder having a prescribed average particle size. The abovementioned method enables a molybdenum carbide granulated powder having the intended average particle size to be efficiently produced at a high yield.
