Zur Phasenanalyse von Mangandioxyd

Abstract: Phasenänderungen, welche bei der Reduktion von Mangandioxydmodifikationen auftreten, werden im allgemeinen mit röntgenographischen Methoden studiert. In dieser Arbeit wird gezeigt, daß man auch durch elektrochemische Messungen Einblick in die Zustandsdiagramme erhalten kann. Mit Hilfe der elektro‐chemischen Methoden kann man unterscheiden, ob homogene oder heterogene Systeme der Oxyde vorliegen; ferner kann man die Grenzen dieser Phasenbereiche genau festlegen. Allerdings gelingt nicht die Charakterisierung de… Show more

“…This result requires further investigation and possibly indicates a failure of equilibrium between the solid phases to be established. The homogeneous region (iii above) is most unexpected in view of Bode et al (2). The transition region between MnO1.4s and MnO1.37s appears to cover a wide range but since the experimental points are relatively widely spaced, a more restricted region corresponding to that found for ~,-MnO2 would not violate the present experimental evidence.…”

“…1 down to MnOL7 corresponds quite well with that found by Bode et at. (2), but the general level of our curve is about 215 my lower. Further, these authors did not observe the sharp change in slope at about MnOl.~ such as reported here.…”
