The in-situ observation of the reaction between iron or iron-oxides and carbon in TEM was carried out. The contact between iron and carbon was realized utilizing the carbon deposition on the surface of iron and FIB enabled to prepare TEM specimens. The reaction occurred around 600℃ as the precipitation of iron and growth into carbon layer. Calcium was also moved to the edge of iron oxides and it indicated that the possibility of the controlling making slag in TEM.
