System Fe₂-O₃-Fe₃O₄ shows two points of transformation, 1 at 590°, corresponding to Fe₃O₄, and the other at 650°, corresponding to a solid solution of Fe₃O₄ in Fe₂O₃. These transformations are rigorously reversible. The system Fe₃O₄-FeO has a transformation point at 570° for the Fe₃O₄. In the system FeO-Fe, the temperature of transformation is the same as that of Fe, or 765°.
