摘要：
A method of preparing a powder, including bombarding a spray gas to a liquid material through a spray nozzle to form an atomized liquid material; and solidifying the atomized liquid material, wherein 5 to 40% by weight of the spray gas are previously mixed with the liquid material to form a two-phase flow in a flow path of the spray nozzle, and 60 to 95% by weight of the spray gas is further discharged from a circumference of the flow path discharging the two-phase flow and bombarded thereto to uniformly atomize the liquid material.
