Synthesis of nano-sized Fe-Co alloy powders by chemical solution mixing of metal salts and hydrogen ruduction(CSM-HR)

초록

Magnetic properties of nanostructured materials are affected in complicated manner by their microstructure such as grain size (or particle size), internal strain and crystal structure. Thus, studies on the synthesis of nanostructured materials with controlled microstructure are necessary for a significant improvement in magnetic properties. In the present work, nanostructured Fe-Co alloy powders with a grain size of 50 nm were successfully fabricated from the powder mixtures of (99.9% pure) FeCl2 and CoCl2 by chemical solution mixing and hydrogen reduction.
