The modern ironmaking emits much CO₂ and the development of new carbon free iron smelting is required now. We found that nitride ceramics reduce iron oxides without CO₂ emission. The iron is formed in Ar atmosphere beyond 1150℃ easily. But it is impossible to see the ironmaking process in bulk condition. We tried to see the iron precipitation directly with in-situ TEM. The video recording of iron precipitation and growth was succeeded. The detailed results of iron making process in TEM will be reported.
