WIPO Patent Application WO/2015/099376
Kind Code:
A1
Abstract:
Provided is a method for manufacturing iron particles comprising ferrite structure and martensite structure by means of decarbonization. The method for manufacturing iron particles comprises : i) a step of providing molten iron; ii) a step of transforming the molten iron into fine particles by atomizing; and iii) a step of providing a plurality of iron particles by decarbonizing the fine particles by applying a decarbonizing gas comprising steam, hydrogen and nitrogen to the fine particles.
