摘要：
A method of manufacturing metallic particulates, comprising the steps of forming a combustion chamber having an oxygen/hydrogen mixed gas injection nozzle, an ignitor, and a metallic material feeder on the upper part of a high-pressure water storage tank filled with inert gas, igniting the oxygen/hydrogen mixed gas injection nozzle by the ignitor to melt (evaporate) a material fed from the metallic material feeder, and bringing the produced molten metal drips into contact with high-pressure water to dip the produced metal particulates into water, whereby the metal particulates with high purity and uniform powder shape and grain size can be manufactured.
