Calculation FeO total to "FeO and Fe2O3" or "FeO and O2"

8/14/20 #2397. Hi Jeongmin, There is no such formula. Most analytical methods only count metals, but report metal oxides. This is why you have a "total" – it's reported as if all Fe was FeO or as Fe2O3. So, assuming you did not specifically measure FeO and Fe2O3 (using titration, Moss, etc), you will never know.

In contrast, through holding at 700°C, since FeO exists stably under this condition as seen in the phase diagram, the Fe 3 O 4 and the Fe 2 O 3 layers changed into a single FeO layer, and thus, the scale comprised one FeO layer. Two-layer (bilayer) scale made up of FeO and Fe 3 O 4 and single-lay-
