1989. ---------------. [KRINGS, W., AND KEMPKENS, J.] [Solubility of Oxygen in Solid Iron. II.] Ztschr. Anorg. Chem., vol. 190, 1930, pp. 313-320; Chem. Abs., vol. 24, 1930, p. 3974.

By measurement of the O₂ pressure of Fe-O mixed crystals with H₂O-H₂ mixtures, the solubility of O₂ in solid Fe at 800° was found to be 0.095±0.01%. At 715° the value of 0.11±0.015% had been previously determined. These results were confirmed by the decomposition of freshly prepared Fe₂O₃ in the same gas mixture.
