<p>The present invention relates to a method of refining a metal powder and, more specifically, to a refining technology of removing sulfur and oxygen in the metal powder without sintering (condensation) the metal powder by maintaining an alkaline earth metal oxide and a powdered mixture consisting of a separating agent such as Al_2O_3, SiO_2, TiO_2, etc.; and a Fe-based, Ni-based, and Co-based metal powder in a temperature range of 700-1300°C under a hydrogen atmosphere.</p> |
