193.    BENEDICKS, C., AND LÖFQUIST, H.  [Solubility of Oxygen in iron of Ferrous Oxide (Oxoferrite, Wüstite).]  Ztschr. anorg. Chem., vol. 171, 1928, pp. 231-238; Chem. Abs., vol. 22, 1928, p. 3612.

                  Diagram given for the system Fe-O (abs. 3053) contradicts the fact claimed by Schenck and Dingman (abs. 3052) that the solubility of O is as high as 2.8% (oxoferrite).  It is only 0.05%.  It has been suggested that traces of Al₂O₃ picked up from the container by Fe₂O₃ would explain the discrepancies.  The solubility of O in a pure Fe-O system is so low that it is difficult to admit that this solubility is increased by the presence of foreign matter, MgO for instance.
