摘要：
An atomizing method for producing metal powder, including splitting molten metal in the vicinity of an exit of a nozzle by introducing the molten metal into a center of the nozzle, wherein gas is flowing through the nozzle. The split molten metal is then further split into fine particles by liquid ejected in an inverse cone shaped flow from a slit surrounding a lower side of the nozzle. The resulting powder is of fine size and spherical or granular shape, and is suitable for metal injection shaping.
