Abstract

A method of manufacturing an iron powder with a low carbon and oxygen content by annealing a crude powder rich in carbon and oxygen, which escape as CO and CO2, comprises passing nitrogen over the crude powder, preferably towards the end of the annealing process. Air may be used as the nitrogen source and the oxygen therein absorbed by increasing the carbon content of the powder.
