The effect of additives on Nano-structure Controlled materials has been studied. This material consists of Fe-based (Fe-Si-Al) soft magnetic metal grains completely separated from each other by insulating thin films. The synthesis process is as follows: first, a metal powder was heated to form thin uniform Al-O-N film (-10nm). Then the coated powder was compacted and hot-press sintered with additives at a high pressure. The sintered materials had electric resistivities (106-108Ω·m) containing B2O3(+5nm-+20nm) higher than that of sintered one without additives.
