Zum chemischen Transport im System MnO unter Berücksichtigng des Sauerstoffkoexistenzdruckes (I)

Abstract: Es wurde der chemische Transport der koexistierenden Phasen Mn2O3Mn3O4 und Mn3O4‐MnO mit Cl2, Br2, I2, HCl, HBr und HI thermodynamisch analysiert und experimentell untersucht. Die genannten Transportmittel sind zum Transport folgender Phasen geeignet: .

“…Anhydrous chromium(II) phosphates are stable towards a disproportionation into chromium phosphides and chromium(III) phosphates despite the instability of "CrO" due to diproportionation into elemental chromium and Cr2O3 . On the other hand, manganese(III)phosphates MnPO4 [15] and Mn(PO3)3 [ 16 exhibit rather low thermal stability and readily decompose t o manganese(II) phosphates and oxygen , despite a much higher thermal stability of Mn2O3 itself [17]. The limits for acid/base stabilisation of low metal oxides are reached , when the metal oxide becomes strongly enough reducing that P4O10 itself is reduced tophosphorus or even phosphide.…”

“…Der Transport von Wüstit ("FeO") und Mangan(II)-oxid ist von Emmenegger [6], Gerlach [7] und Roßberg [8] beschrieben. Beide Oxide lassen sich sowohl mit Chlor als auch mit Chlorwasserstoff endotherm transportieren, wobei Temperaturen um 900°C bei einem Temperaturgradienten von etwa 100°C als Transportbedingungen angegeben werden.…”
