manufacturing method of molybdenum carbide granulated powder and molybdenum carbide granulated powder

摘要

A step Water was poured into a vessel and heated to 50~80 , heating a step of adding a binder to the water which is a step of preparing a molybdenum carbide-containing aqueous solution by placing the molybdenum carbide powder having an average particle size under stirring the water is 1~10 m, of the rotating plate of the spray dryer The rotational speed and A (rpm), when the average particle size of molybdenum carbide granulated powder was as B ( m), A / B is put molybdenum carbide containing aqueous solution to a spray dryer is in the range of 50 to 700, above the rotating plate to disperse the molybdenum carbide-containing solution, and further dried to a manufacturing method of the molybdenum carbide granulated powder which is characterized by having a, a step of preparing a molybdenum carbide granulated powder having a predetermined average particle size is there. According to this manufacturing method, it can be produced efficiently molybdenum carbide granulated powder having an average particle size of interest with high yield.
